Abstract

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.

机械化学活化法优化SiO2/Bi2O3混合物中生物源二氧化硅含量制备高效光催化剂

Bi2O3/Bi2SiO5氧化物光催化剂是通过机械化学活化稻壳中氧化铋（III）和生物源二氧化硅的混合物得到的。利用红外光谱、x射线相分析和x射线荧光分析对材料进行了表征。利用描述甲基橙降解程度与Bi2O3-SiO2体系中SiO2含量关系的数学函数对光催化剂中二氧化硅含量进行了优化。
