摘要: BaBi0.53+Bi0.55+O3 (BBO) with an ordered arrangement of Bi3+ and Bi5+ in the crystal lattice was studied for its photocatalytic activity a view to understand role valency ordering. The visible light BBO towards 4-chlorophenol degradation decreased La3+ substitution. calculated density states showed decrease valence band width ordering concomitant charge transfer between them are vital BBO. substitution reduces by hindering process.
