1Bifunctional S-scheme hybrid heterojunction comprising CdS nanorods and BiOIO_(3) nanosheets for efficient solar-induced antibiotic degradation and highly-selective CO_(2) reduction显示文摘The development of a bifunctional photocatalyst that can be utilized for both energy conversion and envi-ronmental remediation is of great practical significance.In addition,an S-scheme charge transfer process can assist a photocatalyst in efficiently separating photoexcited electrons and holes while maintaining the strong reducibility and oxidizability of the former and the latter,respectively.We developed a bifunctional S-scheme hybrid photocatalyst comprising CdS nanorods and BiOIO_(3)(BIO) nanosheets for efficient antibi-otic degradation and cocatalyst-and sacrificial reagent-free CO_(2) reduction.The combination of visible-light-responsive one-dimensional(1D)CdS and UV-light-responsive 2D BIO resulted in a CdS/BIO hybrid photocatalyst with effective 1D/2D(line)interfacial contact and a broadened optical absorption range.Notably,the CdS/BIO hybrid exhibited exceptional diclofenac degradation and mineralization as well as outstanding CO_(2) reduction activity for CO production,with 95.4%CO selectivity over H_(2)production.The exceptional performance of the hybrid catalyst is primarily attributed to the accelerated photoexcited charge transfer caused by the 1D/2D line interfacial contact and the high charge separation and strong redox power of the separated charges,both of which stem from the effective S-scheme charge transfer process.In addition,photocorrosion of CdS was substantially mitigated,resulting in the high photocat-alytic performance of the hybrid catalyst even after repeated test runs.This study provides insight into the rational design of bifunctional S-scheme hybrid photocatalysts for CO_(2) reduction and pollutant degra-dation.Dong-Eun Lee Naresh Mameda Kasala Prabhakar Reddy B.Moses Abraham Wan-Kuen Jo Surendar Tonda 2023Journal of Materials Science & Technology2023,,30:0
