Abstract:

In this paper, a simulation scenario of organic dye in sewage was constructed, along with the theory of photogenerated carriers-driven reaction of photocatalysts. A comprehensive experiment of green chemistry based on TiO₂/g-C₃N₄ for the photocatalytic degradation of organic dye in water was designed. In the experiment, TiO₂/g-C₃N₄ composite was synthesized by calcination, and its intrinsic structure and degradation performance were studied by X-ray diffraction, transmittance electron microscope, X-ray photoelectron spectroscopy, automatic physical adsorption measurements and ultraviolet-visible spectrophotometry. The comprehensive experiment involves material preparation, detailed characterization, pollutant degradation and other experimental sections to realize the cross-integration of inorganic chemistry, physical chemistry and other disciplines, which bears the concept of green chemistry. Moreover, the experiment is combined with the photocatalytic degradation of inorganic nanomaterials, which is the hot spot in current disciplines. Additionally, it promotes the combination between the theories and practice of synthesis, and more talents in scientific innovation with high ideals can be trained in the process of China's modernization drive.
