摘　　要：催化剂设计创新对于聚对苯二甲酸乙二醇酯(PET)循环利用至关重要。本研究以Fe_(2)(SO_(4))_(3)、ZnSO_(4)·7H_(2)O为原料,采用水热共沉淀法制备铁酸锌催化剂,将其用于降解PET。设计单因素试验与正交试验探究不同制备工艺得到的催化剂对降解性能影响。结果表明:在pH值为11,水热反应时间为11 h,温度为150℃条件下得到的催化剂催化降解效果最好,单体对苯二甲酸二乙二醇酯(BHET)的最大收率为75.13%。Innovation in catalyst design is critical for polyethylene terephthalate(PET)recycling.In this study,Fe_(2)(SO_(4))_(3)and ZnSO_(4)·7H_(2)O were used as raw materials,and a zinc ferrite catalyst was prepared by hydrothermal co-precipitation method,which was used to degrade PET.Single factor experiments and orthogonal experiments were designed to explore the impact of catalysts obtained by different preparation processes on the degradation performance.The results show that at pH=11,the hydrothermal reaction time is 11 h,and the temperature is 150℃,the catalyst has the best catalytic degradation effect,and the maximum yield of the monomer diethylene glycol terephthalate(BHET)is 75.13%.
