Preparation and catalytic performance of CoCuOx-C electrodes in wastewater treatment
The high costs of conventional anode materials constrain the widespread implementation of electrocatalytic oxidation technologies. The carbonized products of HKUST-1 (CuOx-C) and ZIF-67 (CoOx-C) were composited to fabricate a cost-effective CoCuOx-C electrode material in this work. Characterization analyses including SEM, BET, XPS, CV, and EIS demonstrated that the CoCuOx-C electrode with a CuOx-C/CoOx-C mass ratio of 3:1 exhibited superior electrocatalytic activity, achieving a phenol degradation efficiency of 92.18 %. The composite material displayed enriched pore channel diversity, enhanced mass transfer of pollutants, improved electron transport efficiency, and reduced impedance. The CoCuOx-C electrode efficiently degraded pollutants through the generation of abundant hydroxyl radicals (·OH) on its surface. This study provides a significant strategy for improving the economic feasibility of electrocatalytic oxidation technology.
期刊介绍:
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
