Abstract

MoC demonstrates excellent performance in catalysis, and it has been found to possess excellent hydrogen evolution reaction (HER) catalytic activity and highly efficient nitrogen fixation. The catalytic activity of MoC is greatly influenced and restricted by the preparation method. Sintering and carbon deposition, which affect the catalytic activity of MoC, are inevitable in the traditional vapor-solid-solid (VSS) process. In this study, we report the controllable synthesis of α-MoC micron flowers by adjusting the growth temperature a vapor-liquid-solid (VLS) process. The density of the MoC micron flowers is closely related to the concentration of NaMoO aqueous solution. The as-grown MoC micron flowers dispersed with Pt are validated to be an enhanced collaborative electrocatalyst for HER against Pt/VSS-MoC.
