Abstract ：
Upgrading the weak internal electric field (IEF) and slow charge carrier dynamics of carbon nitride (CN) has become a critical focus in photocatalytic hydrogen peroxide (H2O2) generation. In this work, we present intramolecular junction strategy to disrupt the uniform charge distribution within CN frameworks by combining purine-based molecules (Guanine, G and Xanthine, X). The results show that direct incorporation of extrinsic five-membered (G and X) into the uniform triazine frameworks not only regulate the structural symmetry and dipole moment, but also induce a self-polarization effect, thereby enhancing the internal electric field. Furthermore, the differing hybridization modes of the five-membered rings alter the HOMO and LUMO compositions, leading to the spatially effective separation of reduction and oxidation centers. Notably, this structural modification overcomes kinetic barriers, enabling dual-channel H2O2 production. At the same time, this unique structure reduces the conversion barriers of superoxide and hydroxyl radicals, promoting the formation of intermediate reactive species. Consequently, Kelvin probe force microscopy (KPFM) and in-situ XPS further confirmed the successful construction of a robust internal electric field in CN-X, while EPR spectroscopy validated the dual-channel reaction pathways with 9.31-fold increase of H2O2 photosynthesis compared to pristine CN. This work provides pioneering insights into molecular-tailored protocol and dipole field effect, paving the way for advanced solar-to-chemical energy conversion.

Abstract ：
Photocatalytic nitrogen fixation has become a promising strategy to realize artificial ammonia synthesis. Graphitic carbon nitride (g-C3N4, GCN) exhibits significant possibilities for photocatalytic nitrogen fixation, but slow photo-generated electron transfer/separation still restricts its photocatalytic performance. Therefore, we fabricate a novel covalent organic framework (COF) hetero-bridging on g-C3N4 encapsulated with nanocellulosederived carbon (CF) via a simple two-step thermal condensation method. With COF and CF acting as the cocatalysts, the optimum NH3 yield on GCNc/COF can reach up to 238.1 mu mol center dot g- 1 center dot h-1, which is 8.92 times higher than that of the pristine GCN under visible light irradiation. The prominently photocatalytic enhancement of the resultant GCNc/COF is first ascribed to the incorporation of COF (463.6 m2 center dot g- 1) with net-like structure for N2 molecules conspicuous activation/adsorption. Moreover, the coupled cellulosic carbon fibers served as a cocatalyst can not only prolong the light-harvest, but also facilitate the migration/seperation of photogenerated carriers. Therefore, this work provides a probable mechanism for the significantly enhancement of photocatalytic nitrogen fixation and threads for the design of highly active catalysts for NH3 photo-generation.

Abstract ：
Recently, cellulose-based hydrogels have been widely used in biomedical applications. However, obtaining hydrogels with integrated tissue adhesion, sensing, haemostatic and wound healing capabilities remains challenging. In this study, we created a catechol-functionalised hydrogel based on multiple hydrogen bonds and pi-pi stacking using dopamine-modified dialdehyde carboxymethyl cellulose (DCMC-DA) and polyacrylic acid (PAA). The DCMC-DA/PAA hydrogel exhibited strong tissue adhesion, excellent biocompatibility, high sensing performance, effective haemostatic and wound-healing-inducive properties. The abundant aldehyde and catechol moieties of the hydrogels enhanced their adhesion to various substrates. The ions formed by catechol and carboxyl groups endowed the hydrogels with the ability to detect physiological activity signals. Furthermore, the hydrogel demonstrated haemostatic capability, reducing blood loss by 61.1% due to its remarkable adhesion and water absorption capacity. Based on this design strategy of excellent tissue adhesion and biocompatibility, the DCMC-DA/PAA hydrogel considerably accelerated wound healing by accelerating epithelial cell regeneration and collagen deposition. Hydrogels with tissue adhesion, sensing and haemostatic properties exhibit promise for wound healing.

Abstract ：
Photocatalytic H2O2 synthesis (PHS) via graphite carbon nitride (g-C3N4) is a low-carbon and environmentally friendly approach, which has garnered tremendous attention. However, as for the pristine g-C3N4, the PHS is severely constrained by the slow transfer and rapid recombination of photogenerated carriers. Herein, we introduced cellulose-derived carbon nanofibers (CF) into the homojunction of g-C3N4 nanotubes (MCN) and g-C3N4 nanosheets (SCN). A series of photocatalytic results demonstrate that the embedding of cellulose-derived carbon for MCN/SCN/CF composite catalyst significantly improved the photocatalytic H2O2 generation (136.9 mu molL-1h(-1)) with 5-holds higher than that of individual MCN (27.5 mu molL-1h(-1)) without any sacrificial agent. This enhancement can be attributed to the combined effects of the two-step one-electron oxygen reduction reaction (ORR) on conduction band (CB) side and the water oxidation reaction (WOR) on valence band (VB) side. A comprehensive characterization of the mechanism indicates that CF enhances the absorption of light, promotes the separation and migration of photogenerated carriers, and regulates the position of the valence and conduction bands with an effective dual-channel ORR pathway for photo-synthesis of H2O2. This work provides valuable insights into utilizing biomass-based materials for significantly boosting photocatalytic H2O2 production.

Abstract ：
Designing efficient semiconductors for photocatalytic oxygen reduction reaction (ORR) without sacrificial agent is an urgent challenge for H2O2 production under ambient condition. Graphite carbon nitride (g-C3N4) exhibits controllable regulation in band structure and light absorption for photocatalytic process. However, the photo -catalytic H2O2 synthesis by pristine g-C3N4 is poor due to the fast recombination of photogenerated carriers and unfavorable selectivity of ORR. To enhance the photocatalytic H2O2 production, different types of carbon can use in combination with g-C3N4. In the present work, we show how cellulose fiber from bamboo can lead to hybrid C/ g-C3N4 photocatalyst with enhanced photocatalytic activity and H2O2 production rate of 121.75 mu mol center dot L-1 center dot h-1, which is 6.2-fold higher than that of pure g-C3N4 without any sacrificial agent. The experimental results confirmed that TEMPO-cellulose derived hydrophilic carbon can not only accelerate the transfer of photo -generated electrons as well as efficient charge carrier separation, but also promote the sequential two-step single -electron ORR route. Thus, this work provides a pioneering perspective for tuning the electronic interaction between g-C3N4 and cellulosic carbon for enhanced photocatalytic H2O2 synthesis.
