PURPOSE:To obtain a small, light wt. and easily handleable exhaust gas purification apparatus with high capacity, by fixedly depositing perovskite type composite oxide shown by general formula to a heat resistant and corrosion resistant metal net. CONSTITUTION:Provskite type composite oxide shown by general formula A1-xA'xB1-yB'yO3 (wherein A is one element among rare earthe elements, A' is one element among alkaline earth elements, B is Co, B' is one element among V, Cr, Mn, Fe and Ni, O is oxygen.O<1, x<1, O<y<1) is fixedly deposited to a heat resistant and corrosion resistant metal net. The obtained exhaust gas purification apparatus can treat an oxidative gas and a reductive gas in an exhaust gas while is excellent in initial purification capacity and the lowering in the purification capacity thereof is extremely small even if combustion is repeated. In addition, by fixedly depositing composite oxide, the oxidative deterioration of the metal net itself can be prevented and the extension of service life can be attained. |
