综合性实验-氯氧化铋的制备及光催化性能

摘要

介绍了一个化学综合性实验：氯氧化铋的制备及光催化性能。该实验采用溶剂热合成的方法制备了氯氧化铋光催化材料，利用 X-射线粉末衍射和紫外可见漫反射光谱对其进行了表征。最后在全光谱照射下，测试氯氧化铋在不同条件下(pH值和催化剂浓度)光催化降解染料的活性。本实验贯穿材料的制备、表征和性能研究，有利于提高学生的实践能力和对知识的综合运用能力，培养他们的创新能力。%A comprehensive chemical experiment, preparation and photocatalytic properties of bismuth oxide chloride (BiOCl), was demonstrated. BiOCl photocatalytic material can be prepared through solvothermal synthesis and characterized by X - ray powder diffraction ( XRD ) and UV - Vis diffuse reflectance spectroscopy ( DRS ) . The photocatalytic activities of dye degradation over BiOCl were tested under the full spectrum irradiation at different conditions (pH value and concentration of BiOCl). This experiment connects material preparation, characterization and properties study. It is beneficial to improve student’s practice ability and comprehensive ability for knowledge, and cultivate their innovative ability.
