CATALYST FOR PURIFYING EXHAUST GAS FROM CARS COMPRISING OXIDATIVE CARRIER

摘要

PURPOSE: To provide a catalyst for purifying exhaust gas from cars, which shows excellent activity of suppressing oxidation of sulfur dioxide. CONSTITUTION: The catalyst comprising at least one of a cocatalyst selected from the group consisting of a transition metal, an alkaline earth metal and oxides thereof and a noble metal supported on a metal is characterized in that the carrier is an oxidative carrier that is prepared by impregnating at least one metal oxide selected from the group consisting of a chromium oxide, a zinc oxide and a magnesium oxide with a porous medium selected from a titanium dioxide or a zirconium dioxide.
