Abstract  

The molybdate β-Bi2Mo2O9 synthesised by solid state reaction showed photocatalytic activity for the degradation of rhodamine B (rhB), indigo carmine (IC) and alizarin red S (ARS) through a photosensitization process of the organic dye. The activity of β-Bi2Mo2O9 to the degradation of organic dyes was compared with the corresponding γ-Bi2MoO6 phase. It was found that activities exhibited by β-Bi2Mo2O9 were four times higher than that obtained by γ-Bi2MoO6. The extent of mineralization was determined by means of total organic carbon (TOC) measurements, which showed a satisfactory TOC reduction (40%, within 50 h) for rhB.
