MoS2 has been considered as a non-precious alternative to platinum based electrocatalyst for electrochemical hydrogen evolution. Since most of the active site exists on the edges of MoS2, a material design that could increase the exposure of the edges could improve its catalytic activity. In this work, we prepared small sized and few-layered MoS2 that is vertically aligned on three-dimensional interconnected porous carbon nanosheets (IPC). Benefiting from exposure of MoS2 edges, MoS2/IPC composite exhibits a high catalytic activity (225 mA cm(-2) at -250 mV vs. RHE, and Tafel slope of 38 mV dec(-1)) and maintains steady performance for several hours. Since the procedure to prepare MoS2/IPC composites is scalable and cost-effective, our method of preparing few-layered MoS2 on porous carbon shows great potential as a competitive electrocatalysts for HER.
