摘要：

Bi2Ti2O7 crystals with pyrochlore structure were prepared by the chemical solution decomposition (CSD) method. The band gap of Bi2Ti2O7 crystals was estimated to be about 2.95 eV from the onset of UV-Vis absorption spectra of the photocatalyst. The photocatalyst based on Bi2Ti2O7 crystals for photodecolorization of methyl orange was examined. The Bi2Ti2O7 photocatalyst exhibits higher photocatalytic activity than the Degussa P-25.
