Photodeposition of metal sulfides on titanium metal-organic frameworks for excellent visible-light-driven photocatalytic Cr(vi) reduction

Abstract

A series of metal sulfides have been used to sensitize titanium metal-organic frameworks to form heterostructures through a facile photodeposition strategy. Graphene-like MoS 2 sheets, Ag 2 S, CdS and CuS quantum dots were uniformly deposited onto MIL-125(Ti) under ultraviolet light conditions. The as-obtained heterostructure hybrids exhibited interesting photocatalytic activity for Cr(vi) reduction under visible light irradiation.
