摘　　要：采用简单的浸渍、煅烧法制备了CoCu-CaCO_(3)/锯末多孔碳催化剂,考察了催化剂在PMS存在下降解苯酚、亚甲基蓝等有机污染物的催化活性。研究发现,在催化剂CoCu-CaCO_(3)/锯末多孔碳添加量为0.05 g, PMS质量浓度50 mg/L,苯酚与亚甲基蓝的质量浓度分别为10,20 mg/L,5 min内催化剂对苯酚、亚甲基蓝的降解效率分别高达91.24%,98.14%。Co_(3)O_(4)、CuO、CaCO_(3)与锯末多孔碳的协同作用,有效提高了催化剂的催化性能,3次循环后对苯酚的降解率仍高达87%以上,且在降解过程中·SO_4^(-)、^(1)O_(2)和·O_(2)^(-)发挥了重要作用。CoCu-CaCO_(3)/sawdust porous carbon catalyst was prepared by simple impregnation and calcination method.The catalytic activity of the catalyst for reducing organic pollutants such as phenol and MB was investigated in the presence of PMS.In this experiment,the amount of CoCu-CaCO_(3)/sawdust porous carbon was 0.05 g,the concentration of PMS,phenol and MB blue was 50,10 mg/L and 20 mg/L,it was found that the degradation efficiency of phenol and MB was 91.24%and 98.14%,respectively.Moreover,the synergistic effect of Co_(3)O_(4),CuO,CaCO_(3) and sawdust porous carbon effectively improved the catalytic performance of the catalyst.After three cycles,the degradation rate of phenol was still as high as 87%,and·SO_(4)^(-),^(1)O_(2) and·O_(2)^(-)played an important role in the degradation process.
