原位构筑Co-MOFs/碳纤维复合电芬顿阴极及其高效降解四环素
In-situ Construction of Co-MOFs/Carbon Fiber Composite Cathodes and their Efficient Degradation of Tetracycline in the Electro-Fenton System
摘要
Abstract
The traditional Fenton method catalyzes the H 2O2 by Fe2+to generate hydroxyl radicals(·OH),which can efficiently degrade antibiotic organic pollutants in water.However,its wide application is limited by the large amount of iron sludge,the difficulty of Fe2+regeneration and the problems of secondary pollution.The electro-Fenton technology combines electrochemistry and the Fenton oxidation process to significantly improve the efficiency of H2O2 activation.The use of cobalt-based metal organic frameworks(Co-MOFs)as electric Fenton catalysts has high catalytic activity and stability,which can avoid the generation of iron sludge and achieve the purpose of efficient degradation and removal of antibiotic organic pollutants in water.In this paper,Co-MOFs nanocrystalline materials were grown in situ on carbon fiber electrodes,and heterogeneous electric Fenton systems were constructed with the composite material as the cathode and platinum sheets as the anode.By adjusting the preparation method,the type of ligand,the ratio of ligand to metal,the calcination temperature,the system voltage,and the amount of H2O2 added,the optimal preparation conditions were explored:under the hydrothermal condition,Co-MOFs were synthesized by 1∶1 coordination of terephthalic acid and cobalt salt,which were grown in situ on a carbon fiber substrate,and calcined and activated under 100℃in air.The optimal reaction conditions are:the voltage was-0.8 V and the H2O2 addition was 60 μL,and the degradation effect of tetracycline was 91%in 90 min.关键词
