通过次磷酸盐还原法制备磷化镍催化剂，考察了不同Ni/P摩尔比、烧结温度制备的磷化镍催化剂对电催化分解水产氢性能的影响。结果表明，磷化镍产物的结构组成以Ni₂P为主，不同Ni/P摩尔比（1∶2~1∶6）对Ni₂P电催化分解水产氢的性能有重要影响，呈现先增后减的趋势，当Ni/P摩尔比为1∶4时Ni₂P电解水产氢活性最高；此外，在250~550℃范围内，随着烧结温度的升高，Ni₂P电解水产氢的性能呈递减的趋势。

Nickel phosphide catalysts are synthesized by the hypophosphite reduction method.The effects of nickel phosphide catalysts,which are prepared with different molar ratios of Ni/P and at different sintering temperatures,on the performance of electrocatalytic hydrogen evolution are investigated.The results indicate that the prepared nickel phosphide is mainly composed of Ni₂P.In addition,the catalysts with different molar ratios of Ni/P exert an important influence on the performance of hydrogen evolution.As the molar ratio of Ni/P increasing from 1:2 to 1:6,the performance of hydrogen evolution increases first and decreases then.When the molar ratio of Ni/P is controlled at 1:4,the obtained Ni₂P contributes to the highest catalytic activity.Besides,the performance of Ni₂P shows a decreasing trend with the lifting sintering temperature in the range of 250-550℃.
