Graphene Loading Molybdenum Carbide/Oxide Hybrids as Advanced Electrocatalysts for hydrogen evolution reaction

The rational design of cost-effective and high-activity electrocatalyst for hydrogen evolution reaction (HER) is a crucial field of research for achieving the best way to promote “green energy”. Here, we develop a simple route to prepare nanohybrids of three-dimensional graphene loading MoO2Mo2C nanoparticles (MoO2Mo2C/G), which were characterized using X-ray diffractometer (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), demonstrating the MoO2Mo2C/G has unique features with high conductivity, robust structure, and high surface area. The as-developed MoO2Mo2C/G nanohybrid shows great potential to replace Pt-based electrocatalyst for hydrogen evolution reaction (HER) due to its cheapness, high catalytic activity and considerable stability.
