Research Abstract

Rare earth tin oxide supported Rh catalysts were focused as a candidate material for NO reduction in an exhaust gas. The influences of composition of the support material and metal dispersion on the catalytic activity were investigated. The catalytic activity and its degradation were controlled by reduction property of Rh. The reduction of Rh was affected by the composition of both rare earth metal and tin site.
