A structure of a carrier used for exhaust gas purification using an inorganic membrane and a method of producing thereof, in which an inorganic membrane made with an alumina film is produced using anode oxidation and the inorganic membrane is applied to a carrier used for exhaust gas purification, whereby the carrier works in stability at all temperatures and shows a high performance when exhaust gas generated from an engine, such as hydrocarbon, carbon monoxide, nitrogen oxide, and so on, passes through a plurality of shells formed with inorganic membranes. For this, provided is a method of producing a carrier used for exhaust gas purification using an inorganic membrane, including the steps of: (a) applying anode current to each of carrier modules, and loading at least one carrier module in a water tank, in which an electrolyte is circulated and to which cathode current is applied; and (b) forming a porous inorganic membrane on the outer skin of the carrier module. |
