Data for: One-Step Hydrothermal Synthesis of Three-Dimensional Structures of MoS2/Cu2S Hybrids via a Copper Foam-Assisted Method

Description

Recent studies proved that MoS2 is a promising noble metal-free electrocatalyst for hydrogen evolution reaction. Here, we report the three-dimensional (3D) structures of MoS2/Cu2S hybrids were prepared by a one-step hydrothermal method using copper foam. Cu2S derived from the copper foam was used as the self-template of the 3D structures. The MoS2 nanosheet arrays were vertically aligned on the surface of Cu2S networks. The MoS2 nanosheets on the 3D Cu2S structure maximized the exposure of their edge sites at the atomic scale and presented superior catalysis activity for hydrogen production. The ease of composite fabrication suggested that the MoS2/Cu2S composite is a promising candidate electrode material for hydrogen evolution.
