The pentavalent bismuthate BaBi2O6 was prepared by a low-temperature hydrothermal reaction using NaBiO3.nH(2)O and Ba(OH)(2).8H(2)O as starting materials. The X-ray powder diffraction pattern was indexed with a hexagonal cell (space group: P-31m), the same as a PbSb2O6-type crystal. The crystal structure of this compound was refined using synchrotron X-ray powder diffraction data. The cell parameters were found to be a=5.57534(6) and c=5.7381(1) angstrom and the final reliability (R) factors obtained by Rietveld analysis were R-wp=5.15% and R-p=3.62%. This compound exhibited profound photocatalytic activity for phenol decomposition under visible light irradiation.
