| Abstract: | Relationships were obtained between the photocatalytic activity (PCA), absorption spectra, electrical conductivity (σ), and catalytic activity (CA) of oxides containing Zr4+ and Ti4+ and their quantitative and phase composition. It was found that the PCA and CA depend linearly on σ. The relation between these characteristics and the effectiveness of their action in chemical reactions was studied. __________ Translated from Teoreticheskaya i éksperimental’naya Khimiya, Vol. 42, No. 6, pp. 345–350, November–December, 2006. |
