Reticulated ceramic foams prepared from steel making wastes were used as support for preparing Au/Al
2O
3 and Au/CeO
2 catalytic devices. The obtained catalytic systems are active to the 2-propanol oxidation reaction, presenting the Au/CeO
2-coated monolith the best catalytic results because of the combination of the oxidation capability of gold atoms with the redox properties of the ceria phase.

Reticulated ceramic foams, prepared from steel making wastes using an earlier described multilayer replication method, have been used as support for preparing Au/Al
2O
3 and Au/CeO
2 catalytic devices, by depositing a coating of Al
2O
3 or CeO
2 and loading with gold by ion exchange. The obtained catalytic systems are active to the 2-propanol oxidation reaction, presenting the Au/CeO
2-coated monolith the best catalytic results because of the combination of the oxidation capability of gold atoms with the redox properties of the ceria phase.
