摘　　要：利用共沉淀法制备了纳米CuO-Fe_(3)O_(4)催化剂,用X射线衍射与物理吸附仪对催化剂进行了表征。研究了纳米CuO-Fe_(3)O_(4)高效活化过硫酸氢钾降解含酚废水的性能,考察了催化剂的稳定性,讨论了反应的机理。研究结果表明,纳米CuO-Fe_(3)O_(4)中Fe、Cu具有协同效应,与纯相Fe_(3)O_(4)或CuO相比,催化性能显著提高。纳米CuO-Fe_(3)O_(4)高效活化过硫酸氢钾降解含酚废水,在30 min内苯酚去除率可达到92%以上,且pH适用范围广。纳米CuO-Fe_(3)O_(4)催化剂稳定性良好,循环使用4次后去除率仍可达到70%以上。催化剂中的双金属可协同活化过硫酸氢钾,形成高效的氧化降解体系。Nano CuO-Fe_(3)O_(4)was prepared by co-precipitation method and characterized by X-ray diffraction and physisorption analyzer.The performance of nano CuO-Fe_(3)O_(4)efficientlyactivated peroxymonosulfate to degrade phenol-containing wastewater was studied,the stability of the catalyst was investigated,and the reaction mechanism was discussed.The results show that Fe and Cu have synergistic effects in nano CuO-Fe_(3)O_(4),with significantly improved catalytic performance compared with pure phase Fe_(3)O_(4)or CuO.Nano CuO-Fe_(3)O_(4)efficiently activated peroxymonosulfate to degrade phenol-containing wastewater,and the phenol removal rate can reach more than 92%within 30 min,and the pH is widely applicable.Nano CuO-Fe_(3)O_(4)catalyst has good stability,and the removal rate can still reach more than 70%after four cycles.The two metals in the catalyst can synergistically activate peroxymonosulfate,forming an efficient oxidative degradation system.
