Highly dispersed CeO2-x nanoparticles with rich oxygen vacancies enhance photocatalytic performance of g-C3N4 toward methyl orange degradation under visible light irradiation
文献摘要：
CeO2/g-C3N4 photocatalysts have attracted tremendous attention in the photocatalytic degradation of organic pollutants.The design and construction of highly active CeO2/g-C3N4 photocatalysts without harsh conditions are still challenging.Herein,highly dispersed CeO2-x nanoparticles with rich oxygen vacancies were successfully precipitated on the surface of g-C3N4 under mild conditions.The fabricated CeO2-x/g-C3N4 exhibits remarkable activity and stability for photocatalytic degradation of MO pollutant.The optimal rate constant of MO degradation over CeO2-x/g-C3N4 is about 0.031 min-1,which is three times higher than that of g-C3N4.A negligible activity decrease is observed after three cycling runs.The enhanced catalytic performance can be ascribed to the excellent dispersion of CeO2-x with rich oxygen vacancies that benefit O2 adsorption and visible light absorption.In addition,the proper band alignment between CeO2-x and g-C3N4 is conducive to the highly efficient separation of photogenerated electron-hole pairs.
