▎ 摘　　要

NOVELTY - Ozone catalytic decomposition material with low wind resistance and wide humidity comprises 73-92 wt.% of carrier, 1.0-6.0 wt.% of graphene loaded on the carrier, 5.0-15.0 wt.% of manganese oxide, 1.0-5.0 wt.% of low-valent metal ion, 0.05-1.0 wt.% of nano silver, where carrier is a composite material containing nano aluminium oxide or/and porous active carbon. USE - Ozone catalytic decomposition material with low wind resistance and wide humidity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing ozone catalytic decomposition material, which involves (i) soaking carrier in the graphene solution at room temperature for 5-30 minutes, and after being taken out, drying at 50-100 °C to obtain treated carrier; (ii) mixing low-valent metal ion solution and manganese oxide solution to make M-MnxOy solution, and then mixing nano-silver (Ag) and M-MnxOy solution twice to make M-MnxOy-Ag solution; and (iii) soaking treated carrier in M-MnxOy-Ag solution for 4-24 hours, then separating from solid and liquid, and drying at 60-140°C for 3-5 hours.
