8. Catalytic support

The foams concerned by the catalytic support application are also open-structure metal foams.

In most cases, metal foams serve as carriers and thermal conductors and undergo specific surface coatings [B ₅ ] [B ₇ ] which are intended to :

• create a catalytic support and increase the specific surface area,

• adapt the surface material to the chemical reactions required.

Typically, an initial catalytic support layer is deposited (Al ₂ O ₃ , ZrO ₂ , etc.) before the catalyst layer is applied, which makes use of the porosities in the catalytic support....
