Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 , a member of a small group of pure Bi 3+ A site perovskites, exhibiting a high ferroelectric Curie point ( T c ), was rapidly synthesized by a sample method of molten salt synthesis. The purity of Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 samples is directly affected by the reaction conditions such as the soaking temperature, and the heating and cooling rates. The as-prepared Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 particles are well-formed, cube-shaped single-crystals with sizes ranging from 200-300 nm. The chemical states of Bi and Fe ions are Bi 3+ and Fe 3+ in Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 . UV-vis diffuse reflectance spectra and preliminary photocatalytic experiments indicate that the pure Bi 3+ A site perovskite of Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 has a suitable energy bandgap (1.86 eV) and shows obvious photocatalytic activity for the decolorization of methyl blue under visible-light irradiation. The present work suggests potential future applications of Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 in photocatalysis and ferroelectric photovoltaic effects. Pure bismuth A-site perovskite Bi(Mg 3/8 Fe 2/8 Ti 3/8 )O 3 particles were prepared by a sample molten salt synthesis.
