Preparation and characterisation of CuO/Al2O3 films deposited onto stainless steel microgrids for CO oxidation

- Homogeneous alumina washcoating was synthesised onto stainless steel microgrids (MG).
- The alumina washcoat was loaded with different amounts of copper and characterised.
- Three types of copper species were detected in the prepared microreactors.
- The Cu/alumina/MG microreactors were successfully tested in CO oxidation.
- The Cu species distribution seems to play a decisive role in their activity.
