GRAPHITE-LIKE CARBON NITRIDE DOPED MODIFIED MICROSPHERE CATALYST, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

摘要

Provided are a graphite-like carbon nitride doped modified microsphere catalyst, and a preparation method therefor and an application thereof. The active components of the catalyst are CuO and Nd ₂O ₃, and the carrier of the catalyst is g-C ₃N ₄. The preparation method comprises: dissolving copper nitrate and neodymium nitrate in water under a stirring condition, adding dicyandiamide, a templating agent, and an additive in sequence, and ultrasonically forming a mixed solution; subjecting the mixed solution to a hydrothermal reaction, cooling and washing, and drying to obtain precursor powder; and calcining and grinding the precursor powder. A degradation reaction method comprises: mixing the graphite-like carbon nitride doped modified microsphere catalyst, acrylonitrile wastewater, and hydrogen peroxide, and reacting same in a pressure reactor at 160-200°C for 2-6 hours. The catalyst has the advantages of high catalytic efficiency, large specific surface area, reusability, no secondary pollution, and low operating cost.
