Abstract

The invention relates to a composite comprising a layer of porous alumina deposited on a rigid substrate made of β-SiC. The composite can be used as a catalyst substrate. The alumina layer may include catalytically active phases, in particular phases that do not properly bind onto the non-treated β-SiC, such as silver particles.
