Efficient monolithic $ MnO_{x} $ catalyst prepared by heat treatment for ozone decomposition
Abstract The effects of calcined temperature on the properties and ozone decomposition activity of manganese oxide catalysts were investigated under high-humidity, low ozone conditions. An outstanding manganese-based catalyst ($ MnO_{x} $ (260 ℃)) was prepared, which could decompose above 90% (RH =...

| 520 | |a Abstract The effects of calcined temperature on the properties and ozone decomposition activity of manganese oxide catalysts were investigated under high-humidity, low ozone conditions. An outstanding manganese-based catalyst ($ MnO_{x} $ (260 ℃)) was prepared, which could decompose above 90% (RH = 0%) and 70% (RH = 90%) ozone after 6 h using. Specific characterization showed $ MnO_{x} $ (260 ℃) had excellent properties. XRD results showed $ MnO_{x} $ (260 ℃) was mainly $ Mn_{3} $$ O_{4} $ and partially $ MnO_{2} $. TEM indicated $ MnO_{x} $ (260 ℃) exposed highly active crystal family plan $ MnO_{2} $ (110), and the lattice fringes of $ MnO_{2} $ (110) and $ Mn_{3} $$ O_{4} $ (103) overlapped. In situ DRIFT showed hydroxyl groups adsorbed on $ MnO_{x} $ (260 ℃) were removed, which is beneficial to inhibiting the inactivation caused by surface water accumulation. $ O_{2} $-TPD results proven $ MnO_{x} $ (260 ℃) had good oxygen migration ability. XPS results manifested that $ MnO_{x} $ (260 ℃) had the most adsorbed oxygen. In short, when the calcination temperature is appropriate, $ MnO_{x} $ (260 ℃) has coexisted multiple phases, exposed high active crystal family plan and removed surface hydroxyl, which is conducive to the exposure of oxygen vacancies and the inhibition of deactivation. | ||

| abstract |
Abstract The effects of calcined temperature on the properties and ozone decomposition activity of manganese oxide catalysts were investigated under high-humidity, low ozone conditions. An outstanding manganese-based catalyst ($ MnO_{x} $ (260 ℃)) was prepared, which could decompose above 90% (RH = 0%) and 70% (RH = 90%) ozone after 6 h using. Specific characterization showed $ MnO_{x} $ (260 ℃) had excellent properties. XRD results showed $ MnO_{x} $ (260 ℃) was mainly $ Mn_{3} $$ O_{4} $ and partially $ MnO_{2} $. TEM indicated $ MnO_{x} $ (260 ℃) exposed highly active crystal family plan $ MnO_{2} $ (110), and the lattice fringes of $ MnO_{2} $ (110) and $ Mn_{3} $$ O_{4} $ (103) overlapped. In situ DRIFT showed hydroxyl groups adsorbed on $ MnO_{x} $ (260 ℃) were removed, which is beneficial to inhibiting the inactivation caused by surface water accumulation. $ O_{2} $-TPD results proven $ MnO_{x} $ (260 ℃) had good oxygen migration ability. XPS results manifested that $ MnO_{x} $ (260 ℃) had the most adsorbed oxygen. In short, when the calcination temperature is appropriate, $ MnO_{x} $ (260 ℃) has coexisted multiple phases, exposed high active crystal family plan and removed surface hydroxyl, which is conducive to the exposure of oxygen vacancies and the inhibition of deactivation. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2022 |
