Abstract Photocatalytic seawater splitting is an attractive way for producing green hydrogen. Significant progresses have been made recently in catalytic efficiencies, but the activity of catalysts can only maintain stable about 10 h. Here, we develop a vacancy-engineered Ag 3 PO 4 /CdS porous microreactor chip photocatalyst, operating with performance stability exceeding 300 This achieved by establishment both selectivity impurity ions and tailored interactions between vacancies sulfur species. Efficient transport carriers strong redox ability ensured forming heterojunction within space charge region, where visualization potential distribution confirms key design concept our chip. Moreover, separation oxidation reduction reactions inhibits reverse recombination, making capable working at atmospheric pressure. Consequently, presence Pt co-catalysts, high solar-to-hydrogen efficiency 0.81% be whole durability test. When using fully solar-driven 256 cm 2 hydrogen production prototype, H evolution rate 68.01 mmol h −1 m −2 under outdoor insolation. Our findings provide novel approach to achieve selectivity, demonstrate efficient scalable prototype suitable practical solar production.

Abstract Particulate photocatalytic systems using nanoscale photocatalysts have been developed as an attractive promising route for solar energy utilization to achieve resource sustainability and environmental harmony. Dynamic obstacles are considered the dominant inhibition attaining satisfactory energy-conversion efficiency. The complexity in light absorption carrier transfer behaviors has remained be further clearly illuminated. It is challenging trace fast evolution of charge carriers involved migration interfacial reactions within a micro–nano-single-particle photocatalyst, which requires spatiotemporal high resolution. In this review, comprehensive dynamic descriptions including irradiation field, separation transfer, reaction processes elucidated discussed. corresponding mechanisms revealing explained. addition, numerical simulation modeling methods illustrated description field. Experimental measurements characterizations clarified reflection behavior probing detection reactions. representative applications introduced according reported advanced research works, relationships between mechanistic conclusions from variable performance results specific concluded. This review provides collective perspective full understanding thorough evaluation primary processes, would inspired improvement designing solar-driven based on particulate photocatalysts.
