▎ 摘　　要

NOVELTY - Preparing cobalt ferrite-supported graphene aerogel catalyst, comprises (i) dispersing graphene oxide aqueous solution, cobalt salt and iron salt in ethylene glycol to obtain mixed solution, then adding alkali to adjust the pH of the solution to alkaline, uniformly stirring the mixed solution, and dispersing cobalt ions and iron ions on the surface of graphene oxide sheet by electrostatic interaction, (ii) adding mixed solution into a high pressure kettle, heating, reacting under autogenous pressure to obtain graphene oxide hydrogel, and (iii) soaking step (ii) product, washing and freeze drying to obtain final product. USE - The catalyst is useful for degradation and removal of various types of pollutants e.g. phenols, dyes and antibiotics. ADVANTAGE - The method: is simple and suitable for industrial production; and has low cost. The catalyst: has excellent catalytic performance and high efficiency; and is easily recyclable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for cobalt ferrite-supported graphene aerogel catalyst prepared by above method.
