Surfactant-assisted hydrothermal synthesis of rGO/SnIn₄S₈ nanosheets and their application in complete removal of Cr(vi).

ABSTRACT: To solve the problem of contamination of hexavalent chromium (Cr(vi)), visible-light-driven graphene-based ternary metal chalcogenide nanosheets (rGO/SnIn₄S₈) were synthesized via a one-pot surfactant-assisted hydrothermal method for the photoreduction of Cr(vi). Characterizations demonstrated that SnIn₄S₈ nanosheets were uniformly distributed on the surface of rGO and the as-synthesized nanosheets exhibited excellent photocatalytic activity under visible light. In addition, the effects of pH, concentration of critic acid, holes and electron scavengers on the reduction of Cr(vi) were systematically investigated. It was found that 50 mg L^-1 of Cr(vi) could be completely removed within 30 min at pH 2 when citric acid served as a h
