BN/CuAg/CNT composite material and preparation method and application thereof

The invention discloses a BN/CuAg/CNT composite material and a preparation method and an application thereof, and belongs to the technical field of an electro-catalysis material. The space between BNsheet layers and the surfaces of the sheet layers are uniformly adsorbed with Cu and Ag particles in the BN/CuAg/CNT composite material; and CNT has a fixing effect on Ag, Cu and BN. The BN/CuAg/CNT composite material has efficient electro-catalysis oxygen reduction performance and relatively high electrochemical stability; and the preparation method is mild in the overall reaction conditions, free of an organic solvent, safe and environment friendly, simple in post processing, short in flow and low in energy consumption, so that the total cost is obviously lowered. 本发明公开了种BN/CuAg/CNT复合材料及其制备方法和用途，属于电催化材料技术领域。所述BN/CuAg/CNT复合材料中Cu、Ag颗粒均匀附着在BN片层之间及片层表面，CNT对Ag、Cu和BN起固定作用。本发明的BN/CuAg/CNT复合材料具有高效的电催化氧还原性能及较高的电化学稳定性；期制备方法整体反应条件温和，不采用有机溶剂，安全环保，后处理简单，流程短，能耗少，总体成本明显降低。
