Abstract
The present invention relates to a plate-shaped catalyst unit for NOx reduction of exhaust gas, wherein molten metal is sprayed upon surfaces of a metal plate allowing the molten metal to accumulate thereon to form rough surfaces, and the rough surfaces thus obtained are deposited with a catalytic substance for NOx reduction of exhaust gas. The catalyst units thus obtained are each disposed in parallel with the gas flow, and generally arranged across the gas flow and at intervals in the catalytic reactor which is placed in an exhaust gas duct and used as an apparatus for nitrogen oxides (NOx) reduction of exhaust gas.
