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.
