Non-precious metal-based catalysts with low cost and rich reserves are emerging as promising alternatives for Pt-based catalysts for the hydrogen evolution reaction (HER). Herein, we reported a facile and large-scale strategy for Co nanocrystals embedded in a nitrogen-doped carbon matrix through direct carbonization of Co-based metal-organic frameworks (MOFs) in N-2. After carbonization, the ultrafine Co nanocrystals are well dispersed in the nitrogen-doped carbon matrix. We further studied their electrocatalytic properties toward the HER in acidic media and found that the as-prepared catalyst exhibited enhanced catalytic activity and stability.
