Photodeposition of CoOx and MoS2 on CdS as dual cocatalysts for photocatalytic H2 production
文献摘要：
Photocatalytic H2 production from water splitting has a promising prospect for alleviating energy and environmental issues.However,the fast recombination of photogenerated charge carriers limits the pho-tocatalytic efficiency and its practical application.Cocatalyst engineering is an effective strategy to spa-tially separate photogenerated charge carriers.In this work,noble-metal-free MOS2 and CoOx cocatalysts are loaded on CdS nanorods by a two-step photodeposition method.The MoS2 functions as the reduc-tion cocatalyst to trap electrons and CoOx as the oxidation cocatalyst to trap holes.Transmission electron microscopy(TEM),inductively coupled plasma(ICP),X-ray photoelectron spectroscopy(XPS)and Mott-Schottky results demonstrate the effectiveness of photodeposition for loading MOS2 and CoOx dual cocata-lysts on CdS and their impact on the photochemical properties.The optimized CdS-MoS2-CoOx composite exhibits a high photocatalytic H2-production rate of 7.4 mmol g-1 h-1 and an apparent quantum effi-ciency(QE)of 7.6％at 420 nm.Further analysis on time-resolved photoluminescence(TRPL)indicates that the introduction of dual cocatalysts greatly prolongs the lifetime of photogenerated charge carriers and deceases the charge recombination rates,consequently leading to superior photocatalytic H2-production performance.This work provides a facile and effective strategy for the construction of highly efficient dual-cocatalyst-modified CdS photocatalyst for high-performance photocatalytic H2 production.
