Paper Abstract

In this study, a series of calcium bismuthate samples having a different composition and type of crystal lattice was obtained. The diffuse reflectance spectroscopy found that both factors impact the calcium bismuthate ability to absorb the visible light irradiation. It was shown that the bandgap of synthesized photocatalysts depends on the degree of lattice defects. The catalytic activity of photocatalysts was studied in terms of decomposition rate of methylene blue by visible light in the presence of various samples of calcium bismuthate. It was found that the catalytic activity of calcium bismuthates with orthorhombic crystal lattice is lower than that of similar samples of rhombohedral lattice. Thus, samples with the lowest number of cation sublattice defects have the greatest catalytic activity.
