Developing low-cost and highly-efficient electrocatalysts for renewable energy conversion technologies has attracted even-increasing attention.Molybdenum carbide materials have recently emerged as a type of promising catalysts for electrocatalytic reactions due to the earth-abundance and Pt-resembled electrical properties.In this work,taking the advantage of the interaction between the basic groups of the Mo(Ⅵ)-melamine polymer and the acidic groups on the surface of the oxidized carbon nanotubes (CNiTs),N-doped CNTs supported Mo2C nanoparticles (Mo2C/NCNT) are prepared,which exhibit outstanding elec trocatalytic activity and durability for both the hydrogen evolution and oxygen reduction reactions.The impressive performance of Mo2C/NCNT can be attributed to the small size of Mo2C particles,the large exposure ratio of surface sites and the presence of N-doped CNTs.This work enlarges the multi-field applications of molybdenum carbide-base materials as promising non-precious metal electrocatalysts,which is of great significance for sustainable energy-related technologies.
