  • PREPARATION OF THREE-DIMENSIONAL MAGNETIC GAMMA MANGANESE DIOXIDE/ZINC IRON OXIDE NANOHYBRID ON GRAPHENE, AND USE THEREOF AS CATALYST FOR DECOMPOSING HARMFUL ORGANIC WASTE
    Publication number: 20220193641
    Abstract: A nanohybrid includes: reduced graphene oxide (rGO); zinc ferrite (ZnFe2O4) nanoparticles dispersed in the rGO; and manganese dioxide (MnO2) nanoflakes three-dimensionally attached on the rGO. The nanohybrid reduces recombination of graphene through the synergistic effects of MnO2 nanoflakes, ZnFe2O4 nanoparticles, and graphene, and increases the surface area of the catalyst, thus being capable of exhibiting higher catalytic activity than the conventional ?-MnO2@ZnFe2O4, ?-MnO2@rGO, and ZnFe2O4@rGO composites in the decomposition of harmful organic waste.
