Formation of zeolites on metal surface objects, e.g. for combinatorial chemistry work, involves cleaning, etching, treatment with template solution and contacting with zeolite synthesis solution

摘要

The metal surface is cleaned and etched using an organic solvent or peroxide solution and ammonium ions, pre-treated with a template or seed- forming solution and contacted with a zeolite synthesis solution. A method for forming a zeolite on a metal surface of an object (1) involves: (a) cleaning and etching the metal surface by treatment with an organic solvent or peroxide solution, followed by treatment with a solution or liquid comprising or forming ammonium ions; (b) pre-treatment of the cleaned and etched surface using a template or seed- forming solution; and (c) contacting the pre-treated surface with a zeolite synthesis solution. An independent claim is also included for an autoclave device (4) comprising a number of objects, each of which has two or more surfaces upon which a zeolite can be formed.
