Abstract

An exhaust emission control catalyst having an excellent NOx converting capability includes a modified alumina which has a .theta.-phase and an .alpha.-phase and has an .alpha.-conversion rate R in a range of 0.5 %.ltoreq.R.ltoreq.95 %, and a catalytic metal carried in the modified alumina, e.g., platinum (Pt). In addition, a catalyst including a catalyst material which is the above-described catalyst including the modified alumina and the catalytic metal, and an aluminosilicate or cerium oxide (CeO.sub.2), also has an excellent NOx converting capability.
