Effect of cesium incorporation in hydrotalcite-like compounds

To study the spectral regulation of Pr on MgAl2O4 nanoparticles, different contents of Pr doped MgAlPr ternary hydrotalcite were synthesized by co-precipitation method, and Pr containing mixed metal oxides Pr-x-y was prepared by high-temperature calcination. The Pr had little effect on the morphology of hydrotalcite, but significantly improved the heat resistance. The Pr significantly reduced the Eg values of MgAl-L and its mixed oxide ( Eg=1.68–1.87 eV). After 100 min of irradiation with visible light, the degradation rate of MB reached 87.7%. In the reaction system of Pr-0.05-500/H2O2, h+ played a major role. There was a corresponding relationship between the photocatalytic performance and L* value of mixed oxide nanoparticles based on MgAl-L and Pr-0.05-L. The NIR of hydrotalcite or Pr containing nanoparticles was greatly affected by the calcination temperature and Pr containing, but the values of NIR were more than 50%.
