The photocatalytic properties of Bi2-xTi2O7-1.5x (x = 0, 0.5) pyrochlores are examined via ab initio calculations and experiments. A coprecipitation method is applied for the synthesis of nanopowder pyrochlores. The pyrochlore phase formation starts

Combined ab initio and experimental study of Mg-, Ca-, Sr-, Ba-doped bismuth titanate pyrochlores (BTO) has been carried out. It is revealed that the substitution of bismuth atoms by alkaline earth elements is a preferable process rather than the sub

Pyrochlores Mg-, Sc-, Cu-doped bismuth titanates have been obtained. The results of X-ray powder diffraction structure refinement and the pycnometric density measurement point to the preference of the dopants distribution in the A-sites of the pyroch
