摘要
采用配位聚合物法制备Co-吡啶催化剂,制成炭黑负载Co-吡啶光催化剂,考察金属配比、催化剂用量、降解时间、降解温度等对催化降解甲基橙效率的影响。结果表明,金属配比钴∶吡啶=1∶0.5,催化剂用量10 mg,紫外光照6 h时,降解率达82.87%;金属配比钴∶吡啶=1∶1,吸附剂用量20 mg,吸附时间90 min,吸附温度60℃时,吸附降解率达98.1%。
Co-pyridine catalyst was prepared by the method of coordination polymer,to prepare carbonsupported Co-pyridine photocatalyst. The influence of different metal ratio,catalyst dosage,degradation time and degradation temperature on catalytic degradation efficiency were investigated. The results showed that the degradation rate was 82. 87% when the metal ratio（ cobalt∶ pyridine = 1∶ 0. 5）,the amount of catalyst was 10 mg and the UV light was 6 h. At the same time,the adsorption degradation rate was 98. 1%when the metal ratio（ cobalt∶ pyridine = 1∶ 1）,the amount of adsorbent was 20 mg,the adsorption time was90 min and the adsorption temperature was 60 ℃.
