Abstract

Abstract To develop a photocatalyst with novel structure and high performance, a Z-scheme AgSCN/AgCl/FeOCl heterojunction has been successfully prepared by the in-situ synthesis and anion exchange method for the first time. The photocatalytic activity and photo-Fenton catalytic activity of the AgSCN/AgCl/FeOCl nanosheets for the degradation of ibuprofen are 40.7 times and 4.1 times higher than that of FeOCl, respectively. The interfacial structure of the AgSCN/AgCl/FeOCl heterojunction photocatalyst accelerated the separation of the photogenerated electron-hole pairs. The core-shell structure of AgSCN/AgCl effectively suppressed the photocorrosion. This study provides a new approach to the rational design of photocatalysts for emerging environmental applications.
