英文摘要	a novel non-noble electrocatalyst based on molybdenum nitride supported on carbon (mo2n/c) prepared by temperature-programmed reaction (tpr) strategy was investigated as cathode electrocatalysts toward oxygen reduction reaction (orr) in proton exchange membrane fuel cells (pemfcs). the catalyst structure was characterized via x-ray diffraction (xrd). the electrochemical behaviours of the catalyst were investigated by linear sweep voltammetry (lsv) and rotating disk electrode (rde) measurements in 0.5 m h2so4 solution. the reduction of oxygen in acid solution proceeds by an approximate four-electron pathway. the mo2n/c catalyst showed a comparatively good cell performance to oxygen reduction reaction (orr) in pemfcs and has proved to be a promising non-noble electrocatalysts for the alternative of platinum-based catalysts.
