文摘
- •
Metal(Ni, Cu, or NiCu-alloy)-foam-structured Ni–Al2O3 are obtained by a facile wet chemical etching method.
- •
This new approach provides combination of high catalytic performance with enhanced heat transfer and high permeability.
- •
Ni–Al2O3/Ni-foam is highly active, selective and stable for CO methanation.
- •
This catalyst is capable of handling a wide range of syngas mixtures.
- •
Enhanced heat transfer is confirmed by experimental measurement and CFD calculation.
