Ag₂SO₃/AgBr composite was prepared by precipitation-in situ chemical deposition method and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS). Furthermore, the catalytic degradation of a methylene blue solution under visible light irradiation was investigated. This experiment showcases clear phenomena and offers a high level of operability, making it easily accessible for students to acquire a comprehensive understanding of photocatalytic experimental techniques. Moreover, the experiment is closely linked to both cutting-edge research and the fundamental chemistry concepts related to precipitation and dissolution equilibrium, fostering students’ intrinsic motivation to learn and establish a strong connection between college-level chemistry and basic chemistry education. Furthermore, by encouraging students to improve and innovate the experiment from various perspectives, this experiment nurtures their innovative thinking and application abilities, providing valuable training for future chemists in normal universities.
