Summary: A series of linear conjugated polymers were synthesized and used to study the light-driven hydrogen generation from water by adjusting the content of dibenzothiophene-S,S-dioxide (DBTO). It was found that the photocatalytic hydrogen evolution rate (HER) under visible light increased with the increase of DBTO content in donor-acceptor (D-A) structural polymers. The polymer DB-Th showed an unprecedentedly high HER of 334.50 mmol g- 1h-1 under visible-light-driven and cocatalyst-free conditions, demonstrating the importance of acceptor content in D-A structures for achieving ultrahigh photocatalytic hydrogen evolution activity under visible light.

Summary: Triarylamine-substituted benzimidazoliums (BI+- PhNAr2), new electron donor-acceptor dyad molecules, were synthesized and their photocatalytic properties for reductive organic transformations were explored. The results show that irradiation of BI+-PhNAr2 promotes photoinduced intramolecular electron transfer, forming a long-lived charge shifted state. Among the benzimidazoliums explored, the bromo-substituted analogue BI+-PhN(C6H4Br-p)2 in conjunction with BIH-Ph demonstrates the most consistent catalytic performance.

Summary: Photocatalysis provides a low-cost, clean and sustainable process for H2O2 production, but electron-hole recombination and slow reaction kinetics hinder its practical application. The solution lies in constructing S-scheme heterojunctions to enhance carrier separation and boost redox power. This Perspective summarizes recent advances in S-scheme photocatalysts for H2O2 production, including building heterojunctions, H2O2-production performance, and photocatalytic mechanisms. Future research directions and strategies to improve H2O2 yields are suggested.

Summary: In this study, novel structures of graphitic carbon nitride (GCN) were designed by controlling the quantity of NHx(x = 1, 2) and C boolean AND N moieties through a facile NaBH4-assisted calcination of supramolecular assemblies of cyanuric acid and melamine (CM complex). These functional groups acted as donor-acceptor (D-A) motifs in the obtained GCN conjugated polymer, forming a biomimetic D-A system. The structurally modified sample (DCN) showed extended electronic delocalization and enhanced exciton dissociation, thanks to the formation of an internal electric field at the molecular scale. Furthermore, the CM complex endowed the structures with an improved surface area and unique coral-like morphology. As a result, the modified sample exhibited a remarkable photocatalytic H2O2 production rate of 351 μmol h-1 g-1, much higher than that of the pristine sample (CN).

Summary: This study reports a visible light-irradiated Nafion-coated graphene quantum dots/carbon nitride photocatalyst that promotes the splitting of H2O2, resulting in the generation of H2. The Nafion layer on the catalyst surface acts as an impermeable membrane for H2O2 but allows the permeation of H+, facilitating the reduction of H+ and suppressing the reduction of H2O2.

Summary: Covalent organic frameworks (COFs) offer a promising platform for photocatalysts, and their photophysical parameters can be tailored by structural modifications. However, a better understanding of the structure-property-activity relationship, especially in terms of charge-carrier transport, is needed to alleviate the excitonic effect.

Summary: A metal-free carbon nitride material with a tubular morphology and high surface area (CN-nt) is used as a sulfur host in lithium-sulfur batteries (LSBs). The CN-nt effectively disperses active sulfur material and anchors soluble polysulfide species, promoting fast and sustainable Li-S redox reactions. Experimental results show high sulfur utilization, rate capability, and capacity retention for the S@CN-nt electrodes, making this strategy a promising approach for developing cost-effective and metal-free sulfur-based batteries.

Summary: This study investigates the influence of the geometric configuration and composition of ABX spinel catalysts on their catalytic mechanisms and polysulfide conversion. The results show that Co-oh (3+) serves as the active site for breaking S-S bonds, while Co-td (2+) functions as the active site for forming S-Na bonds. This research highlights the subtle relationship between the activity and geometric configuration of spinel catalysts, offering insights for the rational development of improved catalysts by optimizing their atomic geometric configuration.

Summary: Constructing regular three-dimensional structures from two-dimensional nanosheets is challenging but holds great potential for enhancing their functional properties. In this study, the authors synthesized metal-organic frameworks with an orthogonal nanosheet array by epitaxially growing single crystalline nanosheets as shells on a cubic metal-organic framework core. The resulting structure exhibited improved electrocatalytic activity for oxygen evolution compared to conventional nanosheets. The density and size of the nanosheets in the core-shell structure could be adjusted, and metal-organic frameworks with a single composition and hollow orthogonal nanosheet array morphology were also obtained.
