Fabrication of spent FCC catalyst TiO₂-V₂O₅ composite material and its electrocatalytic performance

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.
