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

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.

Chemical Engineering Journal, Год журнала: 2023, Номер 476, С. 146818 - 146818

Опубликована: Окт. 20, 2023

It is an efficient strategy to construct photocatalysts by integrating the advantages of inorganic semiconductors and covalent organic frameworks (COFs) for H2 generation along with simultaneous oxidation. Herein, inorganic/organic CdS/COF (denoted as TpBD) 2D heterostructure fabricated electrostatic self-assembly method. The ultrathin structure can reduce charge transfer distance, enhance light absorption, multiply reaction sites while S-scheme heterojunction improves separation efficiency. composite acquires outstanding photocatalytic activity 15.1 mmol/g/h, simultaneously convert cheap ascorbic acid value-added 2,3-diketo-L-gulonic acid. Hall effect test elucidates dynamics carrier migration. electron paramagnetic resonance analysis, photo-irradiated Kelvin probe force microscopy, femtosecond transient absorption spectroscopy, theoretical calculation, in-situ irradiation X-ray photoelectron spectroscopy measurements confirm superiority transfer. This research presents new inspiration develop hydrogen production green chemical production.
