摘要： 本文围绕环境问题设计了一个综合化学实验。制备了C/Bi/Bi2MoO6复合材料，并对其施加直流电压进行电极化处理，通过扫描电镜和X射线粉末衍射等表征得出电极化法不影响材料的形貌和组成结构，并且能有效增强复合材料的光催化降解活性。本实验实现了化学、环境、能源与材料等多学科交叉融合，实验可操作性强且绿色环保。通过实验改进和仪器表征，激发学生的科研热情，培养创新思维和动手能力。

Abstract: This study presents a comprehensive chemical experiment designed around environmental issues. The C/Bi/Bi2MoO6 composites were prepared and electropolarized by applying direct current voltage. Characterizations, including scanning electron microscopy and X-ray powder diffraction, revealed that the electropolarization process does not alter the morphology and compositional structure of the materials, and effectively enhances the photocatalytic degradation activity of the composites. This experiment facilitates interdisciplinary integration, encompassing chemistry, environment, energy and materials science, offering strong operability and eco-friendliness. Through experimental improvement and instrumental characterization, the study aims to stimulate students’ enthusiasm for scientific research and cultivate innovative thinking and practical abilities.
