摘　　要：以活性炭为担载体,通过一步水热法制备不同比例的氧化钨钼纳米材料,用XRD、循环伏安曲线、线性伏安曲线、电化学阻抗谱对复合材料的性质进行表征和电解水性能研究.结果表明:对不同比例W-Mo-O-C催化剂的析氢性能进行分析,由LSV可以得出W:Mo为1:1比例的W-Mo-O-C催化剂析氢性能最好,起始过电位在150 mV,达到10 mAcm-2的时候,过电位只需要384 mV,较其他比例的W-Mo-O-C催化剂催化性能优越.Different proportions of tungsten oxide molybdenum nanomaterials were prepared by one-step hydrothermal method using activated carbon as the carrier. The properties of the composites were characterized and electrolytic water properties were studied by XRD,cyclic voltammetry,linear voltammetry and electrochemical impedance spectroscopy. The hydrogen evolution performance of W-Mo-O-C catalysts with different ratios was analyzed. From the LSV it can be concluded that the W-Mo-O-C catalyst with tungsten to molybdenum ratio of 1∶1 was the best. The initial overpotential was 150 mV and reached 10 mAcm-2,the overpotential required only 384 mV,which is superior to other ratios of W-Mo-O-C catalyst.
