摘要

本文采用水热法结合化学还原法制备了Ag/CuO纳米材料。采用粉末x射线衍射(XRD)、扫描电镜(SEM)、傅里叶红外光谱(FTIR)、比表面积分析(BET)等方法对合成的Ag/CuO纳米材料进行了表征。研究了化学还原时间、硝酸银浓度对材料合成的影响。结果表明，银晶体被引入到CuO纳米片中。所得Ag/CuO纳米材料的BET比表面积为113.47 m2.g-1。该纳米材料在过氧化氢存在下对甲基橙(MO)的分解具有较高的催化活性。

Synthesis and characteristics of Ag/CuO nanomaterial

In this paper, Ag/CuO nanomaterials were successfully prepared by means of a hydrothermal method combined with chemical reduction. The synthesized Ag/CuO nanomaterials were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), surface area analysis (BET). Two factors influencing the synthesis of materials such as time of chemical reduction, concentration of silver nitrate were studied. The results showed that silver crystals were introduced into the CuO nanosheets. The BET speciﬁc surface area of the obtained Ag/CuO nanomaterial is 113.47 m2.g-1. This nanomaterial has a high catalytic activity for the decomposition of methyl orange (MO) in the presence of hydrogen peroxide.
