Abstract ：
This study experimentally investigates the integration of Fe-Co-Al @ BTC Metal-Organic Framework (MOF) into a double slope solar still (DSSS) to enhance the evaporation rate. Three configurations were tested: MOF as a nanofluid in the basin water (Case I), MOF as a nanofluid with an atomizer (Case II), and MOF for thin film evaporation (Case III). A comprehensive 4E analysis-Energy, Exergy, Economic, and Environmental-evaluated the performance of the DSSS relative to conventional solar still (CSS). The MOF improved DSSS performance through its superior thermal properties and large surface area. Performance results showed notable improvements. Energy efficiency increased significantly, with Case III improving by 103 %, Case II by 82.3 %, and Case I by 53.3 %. Exergy efficiency witnessed more dramatic enhancements, with Case III rising by 162 %, Case II by 137 %, and Case I by 70.6 %. Accumulated distillate followed a similar pattern, with Case III rising by 92.12 %, Case II by 68.54 %, and Case I by 34.66 %. Case III demonstrated the most promising outcomes, achieving the lowest freshwater cost at 0.0122 $/L-a 26.22 % reduction from CSS. Additionally, the MOF integration resulted in CO2 mitigation ranging from 1.49 to 2.2 tons annually, generating carbon credits between 37.13 and 54.94 $/year.

Abstract ：
Halide perovskite nanocrystals (PeNCs) with their exceptional light absorption and tunable bandgap, are promising candidates for solar energy harvesting and high-performance photodetectors. However, the susceptibility of PeNCs to degradation limits their widespread application. The integration of halide perovskites within metal-organic frameworks (MOFs) has recently garnered significant attention as a strategy to create composite materials. The above encapsulation enhances the stability of perovskites against environmental stressors, such as humidity, temperature, and light, leading to improved performance characteristics. This paper provides a comprehensive review of perovskite-metal-organic framework composites (PeMOFs) and their applications in photoelectric conversion. It explores the various preparation methods for PeMOFs and highlights recent advancements in the field. The review examines the specific functions of MOFs within these composite materials and summarizes recent progress in a range of applications, including photocatalysis, sensing, light-emitting diodes, perovskite solar cells, luminescent anti-counterfeiting, information security, and detection. Finally, the paper discusses potential future trends and emerging applications for PeMOFs.

Abstract ：
The growing shortage of freshwater resources has spurred the development of innovative and sustainable desalination technologies. This study presents a thermo-economic analysis of an innovative hemispherical solar still (HSS) enhanced with a novel Metal-Organic Framework (MOF), specifically Iron-Aluminum Benzene Tricarboxylate. The MOF was characterized through structural, morphological, and optical investigations and integrated into the HSS using two enhancement methods: (I) as a nanofluid (MOF-NF) at a 1 wt% concentration in the feedwater, and (II) as a heat localization material (MOF-HL) by dispersing it on a black cotton wick that spans the basin surface. An external condenser (EC) was added to further enhance condensation in a subsequent configuration. Three identical HSS systems were used for comparative performance evaluation: a baseline unit (CHSS) and two modified systems, one with a condenser and one without. The results indicated that both MOFbased approaches significantly improved the thermal performance and freshwater yield of the HSS. Notably, the MOF-HL configuration outperformed the MOF-NF configuration across all performance metrics. The configuration designated as MOF-HL-EC achieved the highest rate of freshwater production, with a 96.16 % increase in distillate productivity compared to the CHSS. Additionally, this configuration exhibited exergy and energy efficiencies of 3.18 % and 61.1 %, respectively-improvements of 80.85 % and 95.72 % over the traditional system. Economically, the MOF-HL-EC configuration reduced the production cost of distilled water to 0.0115$ per liter, marking a reduction of 25.29 %.

Abstract ：
Multistage flash desalination (MSF) is at the forefront of energy-efficient and sustainable water provision, especially with solar energy. This study presents a comprehensive outdoor experimentation of a novel parabolic trough collector-integrated three-stage MSF system. The tests targeted at assessing the impact of various factors, such as varied flow rates and adjusted vacuum settings with/without nanofluid of CuO at 1 %wt, nanocoating, and both. The performance indicators included various system parameters: temperatures, distillation rates, recovery ratios, performance ratios, thermo-economic performance, and water quality. According to the findings, increasing brine flow rates boosted freshwater production but undesirably affected top brine temperature and output quality. That is why the highest daily freshwater output occurred at a flow rate of 30 L/h, while salinity was lowest at a flow rate of 10 L/h. Overall peak efficiencies were of 46.59 % (energy) and of 5.3 % (exergy). Increasing the vacuum inside the MSF chambers improved evaporation but caused brine carryover, negtively impacting the output water quality. Using a 1 %wt nanofluid of CuO enhanced the thermal characteristics, leading to a 17.4 % increase in productivity. Incorporating CuO nanocoating on condenser coils and collector evacuated tubes raised productivity by about 14.5 %, and combining it with CuO nanofluid upgraded this enhancement ratio to 24.29 %. The desalination system demonstrated competitive cost and productivity compared to similar systems.

Abstract ：
To enhance the atmospheric water harvesting (AWH) performance of MIL-160(Al), a series of composite adsorbents were synthesized by incorporating multi-walled carbon nanotubes (MWCNTs) via a hydrothermal method and subsequently loading lithium chloride (LiCl) through an impregnation process. The materials were evaluated in terms of adsorption capacity, desorption efficiency, and cyclic stability. MWCNTs improved structural stability, reducing the adsorption loss to 5.26 % after 30 cycles, while LiCl enhanced water adsorption performance, with equilibrium capacity increased by up to 40.12 % at 80 % RH. The dual-composite system achieved a balance between capacity and durability, showing up to 32.54 % at 80 % RH higher water uptake than pristine MIL-160(Al) and maintained structural integrity and stable performance across 30 cycles. These findings offer support into the rational design of MOF-based sorbents for efficient and long-term AWH applications.

Among boron compounds, NaBH4 has emerged as a prominent candidate for hydrogen energy sources owing to its environmentally friendly characteristics and a high hydrogen content of up to 10.6 wt%. However, the hydrolysis of NaBH4 on catalyst surfaces is an exothermic reaction, necessitating catalysts with high stability and structural strength for efficient hydrolysis. Previous studies have demonstrated that Co-B alloys exhibit favorable catalytic activity for NaBH4 hydrolysis. In this review, we summarize the synthetic methods, catalytic characteristics, applications, and reaction mechanisms of Co-B-based catalysts for further investigation. The report provides an overview of the relationships between the material structures, properties, and applications of Co-B-based catalysts. Firstly, we introduce the hydrogen generation mechanism of NaBH4, followed by a discussion on recent progress in the synthetic methods and catalytic properties of unsupported and supported Co-B-based catalysts. Finally, we summarize details related to Co-B-based catalysts with supporting structures. Notably, among supported structures, exceptional hydrogen generation ability is exhibited by a Co-B/BFS catalyst at 70 410 mL min-1 g-1, while among unsupported structures, the highest HG value is observed with Co-Mn-B at 35 000 mL min-1 g-1. Lastly, we provide a brief outlook on future development prospects for Co-B-based catalysts in NaBH4 applications. Among boron compounds, NaBH4 has emerged as a prominent candidate for hydrogen energy sources owing to its environmentally friendly characteristics and a high hydrogen content of up to 10.6 wt%.

Abstract ：
The integration of thermoelectric generators (TEGs) into industrial processes and multi-generation systems presents a promising solution for recovering low-grade waste heat. This study explores the use of such waste heat in producing green hydrogen, utilizing TEGs as an alternative medium for energy recovery. The hydrogen production methods examined include proton exchange membrane (PEM) electrolyzers and alkaline electrolyzers. The heat sources are categorized into geothermal sources, solar energy sources, and general waste heat sources. By incorporating TEGs into hybrid systems, the overall system efficiency and rated power output, as well as green hydrogen production, are significantly enhanced. For instance, a system combining an organic Rankine cycle powered by a geothermal source with a TEG and a PEM electrolyzer can generate 98.37 kg/day of H2 2 and produce 6781 kW of power, achieving an exergy efficiency of 55.39 %. Additionally, TEGs are employed in hydrogen storage and liquefaction to improve the efficiency of the compression and liquefaction processes by reutilizing waste heat. To provide a comprehensive overview, a bibliometric study using the VOSviewer tool is conducted to highlight the trends in hydrogen production via TEGs, analyzing authors' keywords and index keywords. Moreover, this study presents innovative methods and insights into the efficient recovery and utilization of waste heat for green hydrogen production, emphasizing the potential of TEGs in advancing sustainable energy solutions.

Abstract ：
Cellulose nanofibers (CNFs) have emerged as promising candidates for renewable energy and fresh water applications. A comprehensive comprehension of the intricate interplay between various functional groups of CNFs and water molecules is deemed essential to harness their potential fully. This study delves into the profound implications of functional groups adorning CNFs on multifaceted processes, including photocatalytic water splitting (PWS) and photothermal water evaporation (PWE). Three distinct types of modified CNFs, including 3-chloro-2-hydroxypropyltrimethylammonium chloride modified CNFs (chCNF), oxidative sulfonated CNFs (soCNF1), and directly sulfonated CNFs (soCNF2), were prepared. A comprehensive analysis involving evaporation efficiency assessments, Raman spectroscopy, and molecular dynamics simulations demonstrates that the type and content of functional groups on CNFs significantly influence the state of water molecules. CNFs featuring anionic sulfonic acid groups exhibit superior abilities to regulate the water molecules' hydrogen bonding network structure. Furthermore, bismuth oxychloride nanosheets (BNs) were employed as a photoabsorbent. CNFs were inserted into lamellar membranes to delve deeper into the relationship between functional groups of CNFs and PWS or PWE properties. Notably, the lamellar membrane prepared using soCNF2-2 and BNs achieved a remarkable hydrogen production rate of 13.97 mu mol g-1 h-1, and the PWE rate reached 1.06 kg m-2 h-1 under 1.0 sun irradiation. These findings highlight the potential of CNF functionalization to optimize PWS or PWE processes and provide valuable insights into the interplay between the functional groups of cellulose and water molecules, spanning from molecular interactions to sustainable energy generation and fresh water production. Cellulose nanofibers (CNFs) have emerged as promising candidates for renewable energy and fresh water applications.

Abstract ：
Two-dimensional photocatalytic materials have emerged as prominent materials within ecological and energy catalysis in recent years. Among these materials, two-dimensional Janus structures, including PdXY (X = S, Se; Y = Se, Te), MXY (M = Mo, W; X, Y = S, Se, Te), and MSiGeN4 (M = Mo, W), have been highlighted as prospective candidates for water-splitting photocatalysts. In this paper, we have explored BiSY (Y = I, Br, Cl) as a promising material for overall water-splitting, utilizing first-principles calculations to investigate the geometric structure, stability, electronic structure, and optical properties. By analyzing the results of phonon band structures, molecular dynamics simulations, and the elasticity coefficient, we can establish the system stability of BiSY (Y = I, Br, Cl). And HSE06 energy band calculations and band edge position calculations demonstrated that BiSY (Y = I, Br, Cl) possesses an appropriate band gap. Moreover, the absorption spectra and step reaction diagrams validated the feasibility of photocatalytic water-splitting of BiSY (Y = I, Br, Cl). Additionally, we confirmed that biaxial strain can change the band edge position of BiSY (Y = I, Br, Cl). Our comprehensive analysis shows that BiSY (Y = I, Br, Cl) is a potential candidate for efficient water-splitting photocatalysts. This study contributes to the growing collection of two-dimensional Janus photocatalysts. This study demonstrates the photocatalytic performance of two-dimensional Janus BiSY (Y = I, Br, Cl) based on energy bands, vacuum energy levels, absorption spectra, and reaction potential diagrams.

Abstract ：
Developing conventional solar stills has been given a wide interest being a solution for the water shortage and world energy crises because of simplicity and low energy consumption. As a contribution to these innovation efforts, a 250 W heat pump unit was integrated with a single-slope solar distiller to provide two functions: heating the basin water (by a part of the heat pump condenser) and cooling effect for the extracted vapor from the distiller cavity (via the heat pump evaporator). The other part of the heat pump condenser is subcooled in a separate container via water. The effects of extracted vapor speeds (by varying the fan speed) and different subcooling container temperatures were studied to select the best performance for the modified distiller. The vapor speed tests included 4 variable speeds from 9.33 to 17 m/s. The selected vapor speed was 14 m/s due to its higher corresponding daily cumulative yield of about 10.14 L/m2, which means a 152.63% increasing ratio than that of the reference distiller. Additionally, at a subcooling temperature range of 45 - 50 degrees C, the enhancement ratio increased to 158.5% with a daily water productivity of 10.263 L/m2. The thermo-economic performance was also assessed. From the thermal performance point of view, augmentation ratios of 89.18% and 33.57% were obtained for energy and exergy efficiencies, respectively. Also, for the economic part, the results showed that the freshwater price was 0.0136$/L (for the modified device), which exhibits a reduction of 8.1% than that of the conventional distiller.
