Construction and Optimization of Co(OH)2-ZrO2 Activated PMS System for the Degradation of RhB
In this article,Co(OH)2-ZrO2 catalysts were synthesized by a hydrothermal-precipitation method.The crystal structure of the catalyst was analyzed by XRD,and the morphology and composition were characterized by SEM-Mapping.With Rhodamine B(RhB)as the model contaminant,the cobalt content of the catalyst was optimized under visible light irradiation,and a 10Co-Zr catalyst activated PMS system was then constructed for RhB degradation.The influence of reaction conditions on the degradation of RhB was explored,and the optimal reaction conditions were obtained:initial pH=7.0,PMS=0.5 mM,10Co-Zr=0.1 g/L,resulting in a degradation rate of 98％for RhB.Furthermore,the degradation rate of RhB remained above 95％even after 5 cycles,indicating the acceptable stability and potential application of the catalyst.
