Abstract

Graphene-based materials attract important interest due to their enhanced electron transfer efficiency in photocatalytic hydrogen evolution reactions. In this study, 1D graphene-based nanomaterial combined with ZnO and produced heterostructured CNT/ZnO nanocomposite catalyst enhance the hydrogen evolution. Herein, co-catalysts (MoSx and Pt) were photodeposited onto CNT/ZnO nanocomposite catalyst in water, resulting in the formation of CNT/ZnO/MoSx and CNT/ZnO/Pt through the reduction of (NH4)2MoS4 and H2PtCl6.6H2O, respectively. The photodeposition of co-catalysts on the CNT/ZnO nanocomposite provided enhanced catalytic efficiency and stability due to increased active surface area and enhanced electron transfer capabilities. CNT/ZnO/MoSx photocatalysts are one of the most promising, clean and sustainable energy carrier for photocatalytic hydrogen production.
