摘要

摘要本文介绍了以甘露醇 C6H14O6 为还原燃料通过热解获得的新型陶瓷材料 φ-Bi8Pb5O17 的研究结果。通过使用陶氏构造分析漫反射光谱，确定了所获成分的带隙值。它们在 2.57 至 2.67 eV 之间，相当于可见光光催化剂。使用合成样品，在荧光灯照射 3 小时后，亚甲基橙的降解率为 95% 至 99%。

Effect of Conditions of Mannitol-Nitrate Synthesis on Photocatalytic Properties of φ-Bi8Pb5O17

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.
