Catalytic oxidation of benzene over Ce-Mn oxides synthesized by flame spray pyrolysis

- Ce-Mn oxides for catalytic oxidation of benzene were synthesized by flame spray pyrolysis (FSP).
- Ce-Mn oxides of size <40 nm and specific surface areas of 20-50 m2/g were formed with different Ce-Mn ratios.
- Relative lower benzene conversion temperature (T95 ≈ 260 °C) was achieved by 12.5%-Ce-Mn oxides.
- Better activity was attracted to the synergetic effect of Ce and Mn and small particle sizes as well.
