Title
Novel visible light-induced g-C3N4–Sb2S3/Sb4O5Cl2 composite photocatalysts for efficient degradation of methyl orange
Abstract

•g-C3N4–Sb2S3/Sb4O5Cl2 microspheres were synthesized via a facile hydrothermal method.•MO could be almost decomposed by the component SCL-C2 photocatalyst in 60 min.•O2− and H+ played the main roles in the degradation of the dye.

A series of g-C3N4–Sb2S3/Sb4O5Cl2 (SCL-CX) composite photocatalysts were successfully prepared via a hydrothermal method. The as-prepared materials were characterized by TM3000, powder X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS) and UV–vis diffuse reflectance spectra (UV–vis DRS). The obtained photocatalyst showed higher photocatalytic activity than pure g-C3N4, Sb4O5Cl2 and Sb2S3/Sb4O5Cl2 (SCL). The optimum photocatalytic of the composite with the mass of 170 mg g-C3N4 and a degradation efficiency up to 95% for methyl orange (MO) under visible light was achieved within 60 min. The enhanced photocatalytic performance could be attributed to the stronger absorption in the visible region and the more efficient electron–hole separation.
