Interfacial Engineering of the Platinum/Molybdenum Disulfide/graphitic Carbon Nitride Composite for Enhanced Photocatalytic Hydrogen Production
Source abstract
Abstract
Construction of effective charge separation and transfer channels is a critical issue in photocatalytic energy conversion. In this work, ultrasmall fine Pt nanoparticles and MoS2 nanosheets were deposited on the surface of g-C3N4 as cocatalysts. The presence of MoS2 can effectively induce the structural reconstruction of g-C3N4 and the redistribution of surface charges. The enriched electrons localized in the S and N atoms were conductive to the reduction of Pt4+ and the promotion of the metal–support interaction, thus boosting charge separation and transfer. As a result, the obtained Pt/MoS2/g-C3N4 composite provided a highly photocatalytic hydrogen activity, up to 1595.3 μmol h–1 with an AQE of 30.9% at 435 nm, 87.6 times higher than g-C3N4. This work may provide some insights into the rational design of high-efficient composite photocatalysts for solar energy conversion.
