The γ-Mo2 N electrode prepared by impregnation-calcination method was characterized by XRD, SEM and cyclic voltammetry. The results show that the key to the preparation of γ-Mo2 N electrode by impregnation-calcination method is the selection of heating rate, calcining temperature and time and cooling method. The impregnation-drying temperature has great influence on the uniformity of the polar film and the adhesion of the polar film to the matrix The γ-Mo2 N electrode fabricated under optimized conditions has obvious electrochemical capacitance characteristics, reversible kinetics and good stability and reproducibility during charging and discharging.
