Abstract
PURPOSE: To obtain a purification catalyst for internal combustion engine exhaust gas which converts hydrocarbons and CO with high efficiency and is inert to SO2 by supporting one or more base metal elements out of Mg, Ba, Ca, etc. on a carrier and further supporting one or more noble metal elements out of Pt, Pd, and Rh.
