Abstract
V2O5 and TiO2 have been supported on FCC waste catalyst by modified impregnation method. The composition and morphology of the materials obtained by the characterization results. The relationship between reaction conditions and structure, as well as the close relationship between structure and electrochemical performance were analyzed from the micro level. TiO2-V2O5/FCC has a good porous structure. Using TiO2-V2O5/FCC samples, a three-electrode system was constructed, and the electrode was electrocatalyzed to investigate the degradation efficiency and cycle life of methylene blue dye. The experimental results show that TiO2-V2O5/FCC has good dye degradation and electrocatalytic oxidation performance, which can be used in wastewater treatment and other green chemical industry.
