Deposition process.

摘要

A process for the deposition of a zeo-type material on a porous metallic support, which comprises immersing at least one surface of the porous metallic support in a synthesis gel which is capable of crystallising to produce a crystalline zeo-type material, and inducing crystallisation of said gel so that zeo-type material crystallises on the support; characterised in that prior to immersion in the gel, said surface of the metallic support has been treated with an acid.
