A novel insight of degradation ibuprofen in aqueous by catalytic ozonation with supported catalyst: Supports effect on ozone mass transfer

•CuMn2O4@LR and MnO2–Co3O4@LR showed good application potential and stability.•The above granular catalyst enhanced ozone mass transfer in catalytic ozonation.•CuMn2O4@LR and MnO2–Co3O4@LR catalyzed ozone decomposition to more •OH, •O2−, H2O2.•The large-size supporter is more beneficial for O3 mass transfer than the small one.
