Abstract

L'invention concerne des membranes en oxyde d'aluminium nano-poreuses contenant des clathrates de métaux précieux ou bien des nanoparticules de métaux précieux, ces membranes ayant été obtenues par oxydation anodique et présentant une distribution serrée des rayons des pores. La fabrication s'effectue par revêtement des membranes avec une solution colloïdale de nanoparticules ou de clathrates de métaux précieux stabilisés avec des ligands, séchage et ensuite calcination en présence d'un gaz contenant de l'oxygène. Ces membranes en oxyde d'aluminium présentent un rayon de pore moyen de 1-500 nm avec un écart type de la distribution des rayons des pores de 0-20 %, de préférence de 0-10%. Ces membranes en oxyde d'aluminium contenant des clathrates ou des nanoparticules de métaux précieux conviennent notamment comme catalyseurs lors de la synthèse en présence d'acétate de vinyle.
