Boosting the efficiency and stability of CoMoS4 by N incorporation for electrocatalytic hydrogen evolution

Abstract

Here, an in situ N incorporation method was developed to boost the efficiency and durability of CoMoS₄ electrocatalyst for hydrogen evolution. Theoretical and experimental results reveal that such modification not only reduces the energy barrier of H* desorption by decreasing the electron densities around active metal sites, but also decreases the leaching rates of the metal ions with enhanced stability.
