Abstract
The d-electron structure of ion B in perovskite(ABO3) type oxide has the key role on the binding energy of B-O and the charge-transfer energy(ΔCT) between O2p and B3d, so it has an important influence on the photocatalytic activity of ABO3. In this paper, the species LaBO3(B=Ti-Co) were prepared by the mixed oxide method and the citrate complex method. By analyzing the photocatalytic degradation experiment and their photo-acoustic spectra, the results show that photocatalytic activity of LaBO3 increases with the increasing of d-electron number of ion B.关键词
