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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
