摘　　要：采用一步溶剂热法合成了Co-MOF,然后通过高温焙烧制备了缺陷Co-MOF催化剂。采用X射线衍射光谱仪(XRD)、扫描电子显微镜(SEM)和红外光谱对催化剂进行表征,以甲基橙和刚果红染料为目标降解物,考察了不同Co-MOF衍生物催化剂的催化性能,研究了焙烧温度对催化剂性能的影响。结果表明,缺陷Co-MOF催化剂在甲基橙和刚果红染料的催化还原降解反应中表现出优异的活性和稳定性。其中,于焙烧温度200℃合成的Co-MOF-200催化剂对甲基橙的催化降解效果高于其他焙烧温度合成的Co-MOF衍生物催化剂,这归因于其特殊的缺陷结构和暴露较多活性位点。The Co-MOF is synthesized by one-step solvothermal method,and then the defective Co-MOF catalysts are prepared by high-temperature calcination.The catalysts are characterized by XRD,SEM and infrared spectroscopy.The catalytic properties of different Co-MOF derivative catalysts are investigated with Methyl Orange and Congo Red dyes as the target degradants.The effects of calcination temperatures on the performances of catalysts are studied.The results show that the defective Co-MOF catalysts exhibit excellent activity and stability in the catalytic reduction degradation of Methyl Orange and Congo Red.The complete degradation effect of Co-MOF-200 catalyst synthesized at 200℃is higher than those of other Co-MOF derivative catalysts,which is attributed to its special defect structure and exposure of more active sites.
