Summary: This study developed an AgI/g-C3N4 S-scheme heterojunction with a unique electron transfer pathway as a catalyst for H2 evolution. It was shown that the charge transfer mediated by the S-scheme AgI/g-C3N4 heterojunction was favorable for improving electron utilization in photocatalysis. The S-scheme heterojunction introduced a distinctive electron transfer pathway and prolonged the lifetime of charge carriers, leading to increased electron-reducing ability and improved water chemisorption for photocatalytic H2O splitting.

Summary: Multidimensional hierarchical hollow Co3O4/ZnIn2S4 tubular core-shell heterostructures were prepared by growing ultrathin 2D ZnIn2S4 nanosheets on 1D hollow Co3O4 nanotubes using a solvothermal method. This design not only prevents the self-assembly aggregation of ZnIn2S4 nanosheets, but also broadens their light-absorption range and enhances the utilization of visible light. The p-n heterojunction in the photocatalyst generates an internal electric field, which facilitates the separation and migration of photogenerated charge carriers and effectively suppresses their recombination.

Summary: In this study, in situ Mo-doped and metallic Ni-supported ZnIn2S4-wrapped NiMoO4 step-scheme heterojunctions were developed to enhance the photocatalytic hydrogen evolution reaction (HER) activity of lignin. The S-scheme heterojunctions, formed by the close contact of the two phases, effectively promoted the separation and transport of photogenerated electron-hole pairs. The unique structural design, combined with Mo doping and metallic Ni supports, broadened the light absorption, enhanced the kinetic process of charge transport, and retained strong redox ability, thereby promoting the photocatalytic HER activity.

Summary: In this study, carbon nitride was modified to enhance its photocatalytic performance. A novel nitrobenzene inarched g-C3N4 nanotube photocatalyst (CN-DNP) was successfully fabricated via a facial copolymerization method. The aromatic ring in nitrobenzene could enhance the conjugation of carbon nitride and promote electron delocalization. The introduction of the nitro group enabled electrons to transfer from the center to both ends of the g-C3N4 nanotube, effectively separating the photogenerated electrons and holes. The modified nanotube material showed a narrower bandgap and improved photocatalytic performance.
