摘要 运用程序升温法在不同反应条件下制备γ-Mo2N并用XRD对样品进行表征,不同升温速率及流量下可制备出不同比表面的γ-Mo2N。XRD表明由于合成条件不同γ-Mo2N晶体在结晶方向上为直径4.6nm～18nm颗粒的聚合体。所制备电极用循环伏安法测试表明该电极具有典型的电容行为,其阴阳极电流响应镜像分布,充放电过程动力学可逆性和稳定性良好,其工作电势窗口为0.7V左右,说明γ-Mo2N是一种极具发展前景的储能材料。 In the paper,XRD was used to characterize samplesγ-Mo 2 N prepared by temperature programmed reac-tion of MoO 3 and NH 3 .The samples had different surface areas due to different synthesis conditions.XRD analysis indicated the polycrystallineγ-Mo 2 N was an aggregate of particles ranging in diameters from4.6nm to18nm.Theγ-Mo 2 N electrode exposed to4.4mol/L H 2 SO 4 is determined by cyclic voltammetry and almost mirror-image anodic and cathodic current-response profiles arise,its voltage operating range is only0.6V.The electrode exhibits large capacitance and it had good Faradaic capacitance performances.
