Bismuth ferrite (BiFeO3) and bismuth titanate ferrite (Bi5Ti3FeO15) are studied a
lot in recent years because of their specific structure and potential to act as single phase
multiferrioics. Thanks to the optical band gap energy of 2.3-2.8 eV for BiFeO3 and 1.8-
2.3 eV for Bi5Ti3FeO15, these materials are also interesting for photocatalytic and solar
energy applications, and studies of using Bi5Ti3FeO15 for this purpose are very rare. Solgel
methods were used to produce BiFeO3 and BiFeO3-modified diatomaceous earth,
while Bi5Ti3FeO15 was obtained sol-gel and solid-state methods. These powders were
characterized, and their visible light photocatalytic activity for decomposition of
methylene blue was tested in acidic, close-to-neutral and alkaline conditions. Fenton-like
catalysis was also tested. Influence of synthesis method, microstructure, and catalyst
composition on dye degradation will help in proposing the mechanism of adsorption and
photocatalytic processes.
