Enhanced photocatalytic H2 evolution and anti-photocorrosion of sulfide photocatalyst by improving surface reaction: A review

In situ topotactic formation of an inorganic intergrowth bulk NiS/FeS@MgFe-LDH heterojunction to simulate CODH for the photocatalytic reduction of CO2

“…As is known, sulfides are very susceptible to photocorrosion in the photocatalytic reaction process because photogenerated electrons and holes transfer at different rates, and an excess of either one might result in the photocatalyst becoming inactivated. 45 As a result, the prior research on CODH mimicry with simple sulphides was insufficient (Table S4†), and it is possible that enzyme mimicry can be accomplished via the formation of sulphide bulk heterojunctions. The stability of the NiS/FeS@MgFe-LDHs was therefore evaluated following four photocatalytic cycles (Fig.…”

Efficient degradation of organics by ultrasonic piezoelectric effect on CuO-BTO/AFC composite

“…Recently, the piezoelectric degradation as a new way has attracted increasing attention in the field of catalysis degradation because the built-in electric field generated by piezoelectric effect can promote the separation of photoexcited electrons and holes to successfully achieve redox reactions [12][13][14][15]. All the piezoelectrochemical degradation shared the similar mechanism that the organic molecules were mainly degraded by the free radicals of •OH and •O 2 − excited by the free charges caused via mechanical vibration.…”

Recent advances in CdS heterojunctions: morphology, synthesis, performances and prospects

“…The photocatalysts are firstly excited by sunlight producing photogenerated electron–hole pairs; then the photogenerated electron–hole pairs migrate towards the semiconductor surface; finally, the electrons reduce protons or water molecules adsorbed on the surface of the catalyst to H 2 . 27…”
