Abstract

PURPOSE: To obtain a highly active catalyst with low Rh content by improving a ratio of Rh to Pt in the preparation of a catalyst comprising Pt and Rh supported on a fire resisting carrier for simultaneously removing HC, CO and NOx in exhaust gas from internal combustion engines operated at almost theoretical air-fuel ratio.
