AB In a three-way catalyst for purifying exhaust gases from internal
combustion engines, scattering of bismuth components can be suppressed
by employing a Bi--Ti composite oxide at a predetermined ratio.
Accordingly, the effect of suppressing hydrogen sulfide emissions can be
retained for a long time. This catalyst comprises a support substrate,
and a catalyst layer formed on the support substrate and including a
noble metal, a porous oxide, and a Bi--Ti composite oxide, and satisfies
0.3.ltoreq.R.ltoreq.1.5, where R is the molar ratio of the Bi content to
the Ti content per unit volume of the support substrate.

CLM What is claimed is:
1. An exhaust gas purifying catalyst, comprising: a support substrate;
and a catalyst layer formed on said support substrate and including a
noble metal, a porous oxide, and a bismuth and titanium composite oxide,
the ratio R of the molar amount of bismuth loaded per unit volume of
said support substrate to the molar amount of titanium loaded per unit
volume of said support substrate satisfying 0.3.ltoreq.R.ltoreq.1.5.
...
4. The exhaust gas purifying catalyst according to claim 1 or 2, wherein
the molar amount of bismuth loaded per unit volume of said support
substrate is not less than 0.2 mol/liter and not more than 0.4
mol/liter..
