Abstract

The article presents the results of a study of new ceramic materials φ-Bi₈Pb₅O₁₇ obtained by pyrolysis using mannitol C₆H₁₄O₆ as a reducing fuel. The values of the band gap of the obtained compositions are determined by analyzing the diffuse reflectance spectra using the Tauc construction. They are in the range from 2.57 to 2.67 eV, which corresponds to visible light photocatalysts. The degree of degradation of methylene orange when using synthesized samples ranged from 95 to 99% when irradiated for 3 h with a fluorescent mercury lamp.

硝酸甘露醇合成条件对φ-Bi8Pb5O17光催化性能的影响

摘要

本文介绍了以甘露醇C ₆ H ₁₄ O ₆作为还原燃料通过热解获得的新型陶瓷材料φ-Bi ₈ Pb ₅ O ₁₇的研究结果。所获得的组合物的带隙值通过使用Tauc结构分析漫反射光谱来确定。它们的范围为 2.57 至 2.67 eV，相当于可见光光催化剂。使用合成样品时，用荧光汞灯照射3小时，亚甲基橙的降解程度为95%至99%。
