PHOTOCATALYTIC ACTIVITY OF BiFeO3-BASED POWDERS
Апстракт
Bismuth-ferrite (BiFeO3) is studied a lot in recent years due to its specific
multiferroic properties. Thanks to the optical bandgap energy of 2.3-2.8 eV [1],
BiFeO3-based materials are also interesting for photocatalytic and solar energy
applications. Sol-gel methods were used to produce BiFeO3 and BiFeO3-modified diatomaceous earth. These powders were characterized, and their visible light
photocatalytic activity for decomposition of some organic dyes was tested in acidic,
close-to-neutral and alkaline conditions. Fenton-like catalysis was also tested for
those materials. Influence of synthesis method, microstructure, ageing and
composition on dye degradation helped in proposing the mechanism of adsorption
and photocatalytic processes.
