Abstract

L'invention concerne un composite formé d'une couche d'alumine poreuse déposée sur un support rigide en β-SiC. Ce composite peut être utilisé comme support de catalyseur. La couche d'alumine peut contenir des phases catalytiquement actives, et notamment des phases qui n'adhèrent pas bien sur le β-SiC non traité, telles que les particules d'argent.
