Abstract
MoS2 is a promising catalyst for hydrogen evolution reaction, whereas the inherent defects of limited active sites for H2 evolution and poor conductivity impede its practical application. Herein, low-cost and available activated carbon (denoted as C) was introduced and MoS2/C composite was prepared via a facile one-pot liquid-phased reaction. The MoS2/C exhibits an excellent photocatalytic hydrogen evolution activity (872.3 μmol/h) sensitized by Erythrosin B under LED light irradiation, which is about 1.8 times that of pure MoS2. Moreover, hydrogen evolution mechanism and reasons for the enhanced performance of MoS2/C were proposed based on the results of photoluminescence spectra and photoelectrochemical tests.
