Abstract

BiFeO₃ nanopowders with a size distribution around 20nm and optical absorption onset at 2eV have been synthesized using self-combustion. These particles were used to photodecolourise RhB under AM1.5 irradiation. XPS showed changes to the oxidation state of the Fe cations. Under AM 1.5 illumination at pH 2 RhB showed >95% decolourisation after 10minutes.
