Abstract
A substrate, such as a plate or catalyst monolith, may be coated with a metal oxide, particularly with a zeolite, by treating the substrate with a polyectrolyte to form a coating, and then depositing the coating of metal oxide from an aqueous slurry. A continuous coating, which may incorporate many layers, can easily be formed. In the examples polyacrylamide is used as polyelectrolyte.
