Photoelectrochemical (PEC) water splitting can directly convert solar energy into hydrogen for storage, effectively ending the crisis and solving environmental problems. With their modification by many researchers, photoanodes have rapidly improved in PEC performance. Nevertheless, poor stability of water-splitting devices has not been corrected, seriously hindering practical application large-scale commercialization. In this review, we provide a detailed introduction to photocorrosion mechanism characterizations stability, summarizing current research progress on metal oxide/sulfide photoanode materials. According specificity each semiconductor, corrosion strategy are discussed detail. Finally, summarize deficiencies propose influencing factors possible solutions that need be considered field photoanodes. This review reference based oxides sulfides, especially design efficient stable sulfide-based

Increasing the Photocatalytic Hydrogen Generation Activity of CdS Nanorods by Introducing Interfacial and Polarization Electric Fields

Small, Journal Year: 2023, Volume and Issue: 19(46)

Published: July 20, 2023

Cadmium sulfide (CdS) is a photocatalyst widely used for efficient H2 production under visible light irradiation, due to its narrow bandgap and suitable conduction band position. However, the fast recombination of carriers results in their low utilization. In order improve photocatalytic hydrogen production, it reports successful introduction metallic Cd S vacancies on CdS nanorods (CdS NRs) by facile situ chemical reduction method, using thermal treatment process. This procedure generates interfacial polarization electric fields, that significantly performance NRs sodium sulfite aqueous solutions, irradiation (λ >420 nm). The these fields believed charge separation facilitate faster migration, resulting optimized catalyst, with evolution rate up 10.6 mmol-1 g-1 h-1 apparent quantum efficiency (AQE) 12.1% (420 nm), which 8.5 times higher than CdS. work provides useful method introduce metal photocatalysts build local high-performance production.
