Studies on the Preparation and Photocatalytic Performance of Bismuth Ferrite

Iron oxide and bismuth powder are synthesized by the liquid phase precipitation method. Then a certain proportion of iron oxide, sodium chloride mixed ground to prepare ferrite precursor molten salt The precursors calcined at different temperatures obtain photocatalyst. By studying degradation performance photocatalysts for methyl orange dyes, best conditions dyes found. experimental results show that prepared calcining 750°C has degradation. Compared with single photocatalytic is better.
