▎ 摘  要

NOVELTY - Composite catalyst comprises copper ferrite nanoparticle and graphene oxide supported on copper ferrite nanoparticle. USE - Composite catalyst used for simultaneous desulfurization and denitration of boiler exhaust gas (claimed). ADVANTAGE - The composite catalyst has good magnetic property, is easy to recycle and uses less, and is cost-effective. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1)a method for preparing composite catalyst for simultaneous desulfurization and denitration of boiler exhaust gas, which involves: (a)dissolving ferric nitrate and copper nitrate in absolute ethanol to obtain a first mixed solution;(b)dissolving graphene oxide in absolute ethanol to obtain a graphene oxide dispersion;(c)mixing the obtained first mixed solution and the obtained graphene oxide dispersion;(d)adjusting the pH; (e)performing hydrothermal treatment to obtain a composite catalyst for simultaneous desulfurization and denitration of boiler exhaust gas; and (2)a method for simultaneous desulfurization and denitration of boiler exhaust gas using the composite catalyst, which involves: mixing the catalyst and potassium hydrogen persulfate solution to obtain a mixed solution, adjusting the pH value of the mixed solution, and passing the mixed exhaust gas under heating condition. DESCRIPTION OF DRAWING(S) - The drawing shows an efficiency image of the desulfurization and denitrification under different reaction temperature.
