Guefoams (guest-containing foams) as novel heterogeneous catalysts: Preparation, characterization and proof-of-concept testing for CO2 methanation
The preparation and use of Guefoams as heterogeneous catalyst is reported.The Guefoam catalyst consists of an open-pore Al-Si foam that accommodates a freely mobile guest phase (Ni/CeO2/Al2O3 particles) in its cavities, with neither a physical nor a chemical matrix-guest bond.A eutectic Al-12Si alloy was used as a low-melting matrix Ceiling Fan pre
