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 MoS2 sheets, Ag2S, 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.
