摘要：

Special enhanced synergetic effect of MoS2 quantum dots (MoS2 QDs) and graphene on metal-organic frameworks for photocatalytic hydrogen evolution is obtained here. The photocatalytic activity of H-2 evolution reach 186.37 mu mol over the EY-sensitized 5 rift% MoS2 QDs/UiO-66-NH2/G irradiated under visible light irradiation (lambda >= 420nm) in the first 3 h, and the apparent quantum efficiency (AQE) is 40.5% at 430 nm. The synergistic effect between MoS2 QDs and graphene together with UiO-66-NH2 is corroborated by photo-luminescence spectra, electro-chemical and photo-electro-chemical experiments. It demonstrate that the charge separation and the electrons transfer are more efficient with the aid of the MoS2 QDs and graphene. MoS2 QDs might be a potential photocatalyst for design new type of catalysts in photocatalysis proton reduction. (C) 2017 Elsevier B.V. All rights reserved.
