A substantially complete coating of a zeolite onto a material such as catalyst particles can be achieved by treating the material prior to or simultaneously with zeolite formation, with a polyelectrolye. Copper catalyst systems show good hydrogen storage while blocking access of hydrocarbons to the catalyst.
