Different techniques can be used to apply surface coatings, such as: - Chemical Vapor Deposition (CVD): Used for creating thin films of high-purity materials. - Physical Vapor Deposition (PVD): Involves the condensation of vaporized material onto the catalyst surface. - Atomic Layer Deposition (ALD): Offers precise control over coating thickness at the atomic level. - Electrochemical Deposition: A method where a metal is deposited onto a surface using an electric current.
