文摘
- •
Ni-M (La, Ce, Fe or Co)/ZrO2-clays show excellent catalytic activity for CO and CO2 methanation.
- •
La, Ce, Fe or Co promotes NiO dispersion and enhance the thermal stability of catalyst.
- •
Cerium doped catalyst shows superior catalytic activity to other elements for CO methantion.
- •
Ion doped catalyst shows superior catalytic activity to other elements for CO2 methantion.
- •
High performance is resulted from synergy of doped element, ZrO2 modified clays and nickel species.
