摘要： 应用室温固相反应法制备了NiFe双金属纳米材料，利用X_RD、SEM等技术对合成材料进行了表征，并考察了所合成纳米材料对废水中对硝基苯酚（4-NP）的催化还原性能。结果显示，合成的Ni₅₀Fe₅₀双金属对4-NP的催化还原效果最好，反应速率常数为0.417 min^-1，活化能为7.514 kJ/mol。NiFe双金属纳米材料可作为潜在的优良催化剂用于4-NP废水的处理。

Abstract: Ni-Fe bimetallic nanomaterials has been prepared by room-temperature solid-phase reaction method,and characterized by XRD and SEM. The catalytic reduction capability of synthesized nanomaterials for 4-NP has been investigated. The results show that the catalytic reduction effect of synthesized Ni₅₀Fe₅₀ bimetals on 4-NP is the best,the reaction rate constant k=0.417 min^-1,and activation energy E_a=7.514 kJ/mol. Ni-Fe bimetallic nanomaterials can be used as good catalysts applied to the treatment of wastewater containing 4-NP.

Key words: p-nitrophenol, Ni-Fe bimetals, solid-phase synthesis, catalytic reduction
