ZnCo双金属MOF材料的制备及其催化性能探究

Preparation and Catalytic Performance of ZnCo Bimetallic MOF

以(CH_(3)COO)_(2)Zn和(CH_(3)COO)_(2)Co为金属源,咪唑为有机配体,采用一锅法合成ZnCo双金属节点的金属有机骨架(Metal Organic Frameworks,MOF),将制备的材料用于活化过硫酸盐降解罗丹明B以评估其催化性能。结果显示考所制备的材料具有优异的催化性能,且受pH影响小,在罗丹明B、过一硫酸盐初始质量浓度分别为50和250 mg/L,催化剂投量为0.05 g/L时,罗丹明B在初始pH值为2~10的溶液中反应30 min后,均能被降解90%以上。

Cobaltous acetate and zinc acetate were applied as the metal source,and benzimidazole was applied as the organic ligand to prepare a bimetallic nodes Metal Organic Frameworks(MOF)by one-pot method.To evaluate the catalytic performance,the prepared material was used to activate persulfate for Rhodamine B degradation.The results showed that the prepared material has excellent catalytic performance and less affect by solution pH.When the initial concentrations of Rhodamine B,peroxymonosulfate catalyst dosage are 50 and 250 mg/L and 0.05 g/L,respectively,more than 90%Rhodamine B could be degraded after reacting for 30 minutes with the initial solution pH ranging from 2 to 10.
