Bismuth ferrite (BiFeO3) powders were synthesized by auto-combustion
method. To decrease the quantity of active phase and improve the specific surface
area, composites of BiFeO3 and natural porose materials (diatomaceous earth and
cuttlebone) were prepared by chemical method from solution and calcined at low
temperature. Such obtained powders were used as adsorbents and photocatalysts in
methylene blue water solutions. Nature of photocatalysis under visible and UV-Vis
light was examined under different pH conditions and presence of hydrogen
peroxide, dissolved iron(III), oxalates and some other ions. Methylene blue is
capable to absorb sunlight and insert electrons into semiconductor, so possibility of
this way achieved dye-sensitization was studied [1]. Composites expressed better
properties than individual components confirming the synergetic effect [2]. Acidic
conditions were more suitable for decolorization, so possible Fenton reaction based
homogeneous catalysis was al...so considered.
