Fig. 4: The highly efficient ozone conversion with the 3D hierarchical MnO2@GR.

a Ozone conversion on GO, GR, α-MnO2, GO/MnO2 and 7.50% MnO2@GR, respectively. b Ozone conversion on α-MnO2 and 7.50% MnO2@GR at 50%RH and their regeneration performance (Regeneration condition: 110 °C, air atmosphere). c Ozone conversion on 7.50% MnO2@GR at alternate relative humidity (20% RH and 50% RH). d Ozone conversion of the supported catalyst at 50% RH. Inset: Photos of 7.50% MnO2@GR coated on stainless steel mesh. Experimental conditions: 0.1 g of catalyst (0.25 g for d), 50 ppm O3, flow rate = 900 mL min−1, 25 °C.
