摘　　要：采用静电纺丝法制备钴酞菁/聚丙烯腈纳米纤维(CoTAPc-PAN-NF),并通过XRD和FTIR对其进行表征。选择偶氮染料酸性红(AR1)为目标污染物,探讨了pH、温度、氧化剂浓度等因素对CoTAPcPAN-NF/PMS体系催化性能的影响,结果表明,随着pH(4~7)的升高、温度的升高以及氧化剂浓度的增加,CoTAPc-PAN-NF/PMS体系的催化活性均能得到一定程度的提高。异丙醇(IPA)的加入明显抑制了CoTAPc-PAN-NF/PMS体系的催化活性,而NaCl的加入较大程度上提高了体系的催化效果,从而推测出CoTAPc-PAN-NF催化PMS降解染料的主要活性种是SO_4^-·和HO·。Cobalt phthalocyanine/PAN nanofiber（CoTAPc-PAN-NF） catalyst was prepared by electrostatic spinning. This catalyst was characterized by XRD and FTIR. Azo dye acid red （AR1） was selected as the target pollutant, and the effects of pH, temperature and oxidant concentration on catalytic performance of CoTAPc-PAN-NF/PMS system were investigated, respectively. The results indicate that the catalytic activity of CoTAPc-PAN- NF/PMS system can be improved with the increase in pH （from 4 to 7）, temperature and oxidant concentration. The addition of isopropanol （IPA） has significant inhibition effect on catalytic activity of CoTAPc-PAN-NF/PMS system, while the addition of NaCl largely increases the catalytic effect of the system. Therefore, these results show that CoTAPc-PAN-NF can catalyze PMS to generate SO4^-· and HO· which are the main active species to oxidize dyes.
