摘　　要：利用化学氧化法使苯胺在Ag/AgCl表面原位聚合,制备了聚苯胺-银/氯化银复合材料(PANI-Ag/AgCl)。采用X射线衍射(XRD),紫外-可见光谱(UV-vis)对该复合材料进行表征。然后以甲基橙(MO)为模拟污染物,对比研究了Ag/AgCl和PANI-Ag/AgCl对该模拟染料废水的光催化降解活性。结果显示,光照30 min后,单独的Ag/AgCl对MO的降解率约为65%;而PANI-Ag/AgCl对MO的降解率达到了99%。循环使用4次,PANI-Ag/AgCl对MO的降解率不变。Polyaniline-silver/silver chloride （PANI-Ag/AgCl） composite is produced from situ polymerization of an- iline on the surface of silver chloride by the method of chemical oxidation. The samples are characterized by X-ray diffraction （XRD） and UV-vis diffuse reflectance spectroscopy. Then, a comparative study of the photocatalytic deg- radation activity of Ag/AgCl and PANI-Ag/AgCl toward methyl orange （MO） as the simulated pollutant is carried out. Experimental results show that the degradation rate of Ag/AgCl toward Mo is 65% when singularly used where- as that of PANI-Ag/AgCl reaches 99%. In addition, its degradation rate remains the same even after been cycle used for four times.
