PANI/Fe-杭锦2#土催化剂对乙酸的光催化降解研究

论文摘要

首先采用Fe掺杂杭锦2#土为载体,聚苯胺（PANI）为活性组分,使用原位聚合法制备了PANI/Fe-杭锦2#土负载型光催化剂,采用红外光谱（IR）、X射线光电能谱（XPS）、氮气吸附脱附（N2-BET）、透射电子显微镜（TEM）和固体紫外可见漫反射（UV-Vis DRS）等手段对催化剂进行表征.选用乙酸为降解物考察催化剂的催化活性及稳定性.探究了催化剂中PANI活性组分负载量、反应光源及催化剂用量等反应条件对催化剂催化性能的影响.实验结果表明,室温可见光下,使用0.07 g用量的PANI负载量为5%的催化剂,对10 mL初始浓度为80 mg·L-1的乙酸溶液反应6 h后其降解率达到62.3%,表现出较好的催化活性.
