Covalent organic frameworks have attracted widespread attention in the field of photocatalytic hydrogen evolution, but their limited light capture ability and charge transfer efficiency still limit performance. Catalysts based on single-crystal semiconductors unique crystal faces show great potential for applications fields energy environment. Here, an organic-inorganic semiconductor heterojunction donor-acceptor covalent framework (COF) has been developed, utilizing intramolecular interfacial built-in electric to enhance mobility photo-generated carriers. Specifically, a COF containing thiophene groups is synthesized through Schiff base reaction, which activates (002) plane CdS by reacting with snowflake-shaped CdS. strong π conjugated structures unevenly distributed electrons surface provide large number reaction system. The synergistic effect CdS/COF heterostructures significantly improves migration carriers, allowing more migrate active sites evolution reaction. This work introduces photocatalyst frameworks, opening up new path efficient clean conversion.

Abstract The need to constrain the use of fossil fuels causing global warming is motivating development a variety photocatalysts for solar‐to‐fuel generation and chemical synthesis. In particular, semiconductor‐based have been extensively exploited in solar‐driven organic synthesis, carbon dioxide (CO 2 ) conversion into value‐added products, hydrogen (H from water O) splitting. Recently, metal halide perovskites (MHPs) emerged as an important class semiconductors heterogeneous photocatalysis owing their interesting properties. Despite key issues with long‐term stability degradation polar solvents due ionic character, there has significant progress perovskite‐based improving performance gas liquid phases. This review discusses state‐of‐the‐art using photoelectrocatalysis production halogen acid solutions, CO reduction chemicals, various transformations. different types used, design strategies overcome instability solvents, efficiencies achieved are discussed. Furthermore, outstanding challenges associated electrolytes how can be improved

Abstract Z‐scheme systems based on two‐step photoexcitation are thought to be a promising means of converting solar energy into hydrogen using long‐wavelength visible light. Electron transfer between the evolution photocatalyst (HEP) and oxygen (OEP) can greatly affect performance such systems, use electron mediators providing efficient is thus helpful. Ionic redox couples have been widely employed in particle suspension this regard. In ions diffuse through stirred solution react HEP OEP. Solid‐state also promote while simultaneously holding OEP place. This convenient immobilizing particulate photocatalysts may applicable large‐scale production. Accordingly, it would desirable increase efficiency charge by combining various solid‐state conductors. The present review examines latest advances water splitting focusing mediators. Both immobilized assessed. Potential approaches construction operations discussed detail together with important future challenges.

Solar-driven hydrogen generation is one of the promising technologies developed to address world’s growing energy demand in an sustainable way. While, for (otherwise water splitting), photocatalytic, photoelectrochemical, and PV-integrated splitting systems employing conventional semiconductor oxides materials their electrodes have been under investigation over a decade, lead (Pb)- halide perovskites (HPs) made debut 2016. Since then, exceptional characteristics these materials, such as tunable optoelectronic properties, ease processing, high absorption coefficients, long diffusion lengths, positioned them highly material solar-driven splitting. Like solar photovoltaics, field also dominated by Pb-HPs with ongoing efforts improve stability evolution/generation rate (HER).
