Ag₃VO₄/g-C₃N₄/diatomite ternary compound reduces Cr(vi) ion in aqueous solution effectively under visible light.

ABSTRACT: In recent years, the conversion of Cr(vi) to Cr(iii) ions by semiconductor photocatalysis technology has been considered to be an effective method to solve this problem. In this paper, a kind of ternary composite, Ag₃VO₄/g-C₃N₄/diatomite (AVO/CN/DT), was synthesized by a two-step method (annealing-precipitation). Through a series of characterization analyses, the crystal morphology, microstructure, optical properties and photoelectrochemical properties of the material were characterized and analyzed. The band edge of g-C₃N₄ was red-shifted due to the addition of Ag₃VO₄ and diatomite. Consequently, the visible light response of the composites was intensified. Taking Cr(vi) in aqueous solution as a target
