Abstract:

Four main phases in Ca-Bi-O systems, Ca6Bi6O15, Ca4Bi6O13, CaBi2O4 and Ca5Bi14O26 were prepared by solid-state reaction method. UV-visible absorption spectra show that the samples of CaBi2O4, Ca4Bi6O13 and Ca5Bi14O26 have visible-light reactivity with the band gap of 3.08 eV, 2.76 eV and 2.60eV, respectively. The results of SEM and BET measurements indicate that CaBi2O4 has the morphology of flower-like nanostructure and the high BET surface area, while Ca6Bi6O15, Ca4Bi6O13, and Ca5Bi14O26 have the morphology of particles of various shapes with a diameter from 200 nm to 2 μm and low BET surface area. CaBi2O4 was found to be a most efficient visible-light-driven photocatalyst in degradation MB. This work may deepen the understanding of the relationship between the photocatalytic properties and the crystal structures in Ca-Bi-O system.
