文摘
- •
On MeOx/ZrO2 (Me = Co, Cu, Fe, Mn) isolated Men+ are active for N2O decomposition.
- •
The mobility of Men+ oxidation state is a key factor for activity.
- •
The effect of zirconia-doping is to change the mobility of Men+ oxidation state.
- •
Electron-withdrawing sulphates hinders Me(n+1)+O− formation and deN2O activity.
- •
Electron-releasing K+ induces easy formation of Co3+O− and high activity for deN2O.
