Photo catalytic activity of rare earth La(Y)/rutile TiO2

摘要：

The rutile TiO2, La/rutile TiO2 and Y/rutile TiO2 were synthesized by one-step method, and the densities of states were investigated by ab initio method. Firstly, the result of ab initio calculation showed that the band gap of La/rutile TiO2 is less than that of Y/rutile TiO2 and rutile TiO2, and the crystal lattice energy of rare earths (La, Y)/rutile TiO2 are similar to each other. Secondly, the crystal structure and photocatalytic activity of La (Y)/rutile TiO2 are characterized by XRD, DRS, ζ potential and kinetics reaction of photocatalyzing methyl orange. In a word, the photocatalytic activity for degradation of methyl orange on 1.0wt% La/rutile TiO2 was better than those on Y/rutile TiO2 and rutile TiO2.
