Preparation of defect-enriched (SiO32-, Cu2+) –α-Fe2O3/MoS2 Z-scheme composites with enhanced photocatalytic-Fenton performance
Source abstract
Abstract
Construction of Z-scheme photocatalyst is of great attention. Herein, the (SiO 3 2-, Cu 2+) – α-Fe 2O 3 (SCF) with abundant oxygen vacancies (OVs) was obtained, and defect-enriched SCF/MoS 2 direct Z-scheme composites were successfully prepared using a hydrothermal method. The composites exhibited higher photocatalytic-Fenton activity compared with single-component SCF and MoS 2. The as-prepared SCF/MoS 2 -2 was found to be an effective visible-light-driven photocatalyst for p-nitrophenol (p-NP) degradation. Under the synergetic action of OV defects, photo-Fenton, and Z-scheme heterojunction, more active species were produced in the degradation system, thereby resulting in the rapid degradation of p-NP.
