摘要：

A novel electrocatalyst of layered MoS2 supported on reduced graphene oxide (RGO) decorated with nano-sized tungsten carbide (WC) shows an enhanced catalytic performance in the hydrogen evolution reaction, which could be attributed to the presence of a conductive and electrocatalytically-active nano-WC dispersant and the positive synergistic effect between nano-WC/RGO and layered MoS2.
