摘　　要：本研究探讨了纳米薄片状氯氧化铋的制备方法及其在热解过程中的行为。采用室温下水解法制备氯氧化铋,形貌为近似圆角状的长方形结构。通过热重分析和X射线衍射分析,研究了氯氧化铋在不同温度下的热解行为,发现其在600℃开始分解,产物为BixCly、BixOyClz、Bi_(2)O_(3),于800℃分解结束,最终生成Bi_(3)O_(4)Cl。光催化性能评价结果表明,制备的氯氧化铋及其热解产物在降解有机染料甲基橙方面表现出优异的光催化性能。本研究为纳米薄片状氯氧化铋的制备与应用提供了重要的实验依据。In this study,the preparation method of nano flake Bismuth oxychloride and its pyrolysis behavior were discussed.Bismuth oxychloride was prepared by hydrolysis method at room temperature,and its morphology was rectangular with rounded corners.Through Thermogravimetric analysis and x-ray diffraction analysis,the pyrolysis behavior of Bismuth oxychloride at different temperatures was studied.The evaluation results of photocatalytic performance showed that the prepared Bismuth oxychloride and its pyrolysis products showed excellent photocatalytic performance in the degradation of organic dye Methyl orange.This study provides an important experimental basis for the preparation and application of nano flake Bismuth oxychloride.
