Abstract: A reactor for corona destruction of volatile organic compounds (VOCs), a multi-surface catalyst for the reactor and a method of making the catalyst for the reactor. The reactor has a catalyst of a high dielectric material with an enhanced surface area. A catalyst layer stack is formed by depositing a high dielectric layer on a substrate and, then depositing a conductive layer on the dielectric layer. The catalyst layer stack is bombarded by low RF energy ions to form an enhanced surface area and to form a protective layer over the conductive layer. Catalyst layer stacks may be joined back to form double-sided catalyst layer stacks. The catalyst layer stack may be diced into small pieces that are used in the reactor or the whole catalyst layer stack may be used.
