A CN-supported Mn3O4（Mn3O4-CN）composite was synthesized as a catalyst for the catalytic ozonation of 2,3-dimethylpyrazine degradation in wastewater. The catalytic efficiencies of 2, 3-dimethylpyrazine were investigated under various ozone dosages, catalyst dosages, pH and temperature conditions. The results showed that under the conditions of an ozone dosage of 3mg/L, a catalyst dosage of 0.02g/L, pH =7 and a temperature of 10℃, the degradation rate of pollutants reached 100% within 20 min. Scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction and other characterization methods were used to analyze the properties of the prepared Mn3O4-CN. It was confirmed that Mn3O4 and CN were successfully bonded, and the valence states of Mn were mostly +2 and +3. The reactive oxygen species analysis demonstrated that the surface hydroxyl groups and oxygen vacancies were identified as the main active sites, and ⋅OH was the main active oxygen species generated in the reaction system. The cyclic experiments showed that the Mn3O4-CN has good stability and reusability.
