Abstract: The present invention discloses a graphite-like carbon nitride-doped modified micro-spherical catalyst and a preparation method and a use thereof. The active components of the catalyst are CuO and Nd 2 O 3 , and the carrier of the catalyst is g-C 3 N 4 . The preparation method comprises: dissolving copper nitrate and neodymium nitrate in water while stirring, adding dicyandiamide, a template agent and an auxiliary agent sequentially, and performing ultrasonic treatment to form a mixed solution; subjecting the mixed solution to a hydrothermal reaction, cooling, washing and drying to obtain precursor powder; and calcining and grinding the precursor powder. The use in a degradation reaction comprises mixing the graphite-like carbon nitride-doped modified micro-spherical catalyst with acrylonitrile wastewater and hydrogen peroxide and making the mixture to react for 2-6 h at 160-200 °C in a pressure reactor. The catalyst provided by the present invention has advantages of high catalytic efficiency, large specific surface area, reusability, lack of secondary pollution, and low operation costs.
