摘　　要：通过简易水热法合成了Ag-ZnO纳米材料,采用SEM、EDS、XRD和XPS等表征手段对所制备的纳米材料进行了表征,并将其作为催化剂用于对硝基苯酚(4-NP)的还原反应。结果表明,Ag-ZnO纳米材料可在8 min内催化4-NP还原生成对氨基苯酚(4-AP),催化效率高达99.5%,且在第5次循环反应时催化效率仍保持在90%左右,具有较高的催化活性,循环使用寿命长。Ag-ZnO nanomaterials were synthesized by a simple hydrothermal method,and the nanomaterials were characterized by SEM,EDS,XRD and XPS.This were used as catalysts for p-nitrophenol(4-NP)reduction reaction.The results show that Ag-ZnO nanomaterials can catalyze the reduction of 4-NP to p-aminophenol(4-AP)within 8 min,with a catalytic efficiency of up to 99.5%.The catalytic efficiency remains at about 90%in the fifth cycle of the reaction.The Ag-ZnO nanomaterials have high catalytic activity and long cycle life.
