▎ 摘　　要

NOVELTY - A three-dimensional manganese dioxide doped zinc ferrite/reduced graphene oxide (rGO) nanohybrid catalyst comprises a reduced graphene oxide (rGO), zinc ferrite nanoparticles dispersed in the rGO, and manganese dioxide nanoflakes attached in the three-dimensional on the rGO. USE - Three-dimensional manganese dioxide doped zinc ferrite/reduced graphene oxide (rGO) nanohybrid catalyst used for decomposing hazardous organic waste (claimed). ADVANTAGE - The nanohybrid catalyst has excellent catalytic activity and reusability, and reduces the aggregation of graphene and increasing the surface area of the catalyst through the synergistic effect of nanoparticles. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a catalyst, which comprises the nanohybrid catalyst and peroxymonosulfate (PMS); and (2) manufacture of nanohybrid catalyst, which involves dispersing zinc ferrite nanoparticles in a graphene oxide (GO) solution to prepare zinc ferrite/GO solution, adding a manganese precursor and an acid to the obtained solution to form suspension, and heat-treating the suspension to form a three-dimensionally reduced graphene oxide in which zinc ferrite nanoparticles are dispersed.
