摘　　要：Tailor-made advanced electrocatalysts with high active and stable for hydrogen evolution reaction(HER)play a key role in the development of hydrogen economy.Herein,a N,P-co-doped molybdenum carbide confined in porous carbon matrix(N,P-Mo_(2)C/NPC)with a hierarchical structure is prepared by a resources recovery process.The N,P-Mo_(2)C/NPC compound exhibits outstanding HER activity with a low overpotential of 84 mV to achieve 10 mA/cm^(2),and excellent stability in alkaline media.The electrochemical measurements confirm that the enhanced HER activity of N,P-Mo_(2)C/NPC is ascribe to the synergy of N,P-codoped and porous carbon matrix.Density functional theory calculations further reveal that the electron density of active sites on Mo_(2)C can be regulated by the N/P doping,leading to optimal H adsorption strength.In this work,the proof-of-concept resource utilization,a microorganism derived molybdenum carbide electrocatalyst for HER is fabricated,which may inaugurate a new way for designing electrocatalysts by the utilization of solid waste.
