Abstract
PURPOSE:To obtain a catalyst having purifying capacity even if a supporting amount of a noble metal is low, as a catalyst for purifying an exhaust gas, by supporting a noble metal catalytic component on a catalyst carrier containing tungsten. CONSTITUTION:As a catalyst for purifying an exhaust gas, on a catalyst carrier comprising containing tungsten in a carrier component such as alumina, cordierite or the like, a noble metal component such as platinum, rhodium or the like is supported. Thus prepared catalyst simultaneously purifies CO, HC, NOx or the like in an exhaust gas from an internal combustion engine, especially, an automobile but, even if a supporting amount of the noble metal is low, purifies the same with high activity.
