EFFECTIVE LOW-TEMPERATURE CATALYTIC METHANE COMBUSTION OVER Mn-CeO2 CATALYTIC COMPOSITIONS

Methane is currently considered the second most damaging greenhouse gas, since it has a GWP (Global Warming Potential) ranging from 28 to 36 over 100 years, being also the precursor for stratospheric ozone formation. The present study is aimed to prove the catalytic behaviour in the methane combustion, up to 600 °C, of a series of nanocomposite materials, based on MnCeO2 compositions (0.3<Mnat/Ceat<9), with enhanced textural, redox and catalytic properties (Table 1), prepared via a new eco-friendly synthsis route.
