Room-temperature catalytic removal of low-concentration NO over mesoporous Fe-Mn binary oxide synthesized using a template-free approach

- Mesoporous Fe-Mn binary oxide with high surface area of 240 m2/g was synthesized.
- Room-temperature catalytic removal of 10 ppm NO was firstly reported.
- 100% removal of NO for 4 h at a high space velocity of 40,000 h−1 was realized.
- NO was catalytically converted to NO2 and then adsorbed or absorbed as nitrates.
- A synergetic effect between Mnn+ and Fen+ was proposed for the catalysis process.
