Optimization of Biogenic Silica Content in SiO2/Bi2O3 Mixture for Obtaining Efficient Photocatalysts by Mechanochemical Activation Method
Bi2O3/Bi2SiO5 oxide photocatalysts are obtained by mechanochemical activation of a mixture of bismuth(III) oxide and biogenic silica from rice husks. The characteristics of the materials are presented using IR spectroscopy, X-ray phase analysis, and X-ray fluorescence analysis. The silica content in the photocatalysts is optimized using a mathematical function describing the dependence of the degree of methyl orange degradation on the amount of SiO2 in the Bi2O3–SiO2 system.
