Embodiments of the present disclosure include a catalyst for the conversion of CO and/or hydrocarbons in an exhaust stream including a Sn compound selected from the group consisting of a binary composition comprising Sn and Ti, a ternary composition comprising Sn, Ti and Zr, and mixtures of any thereof. In those embodiments, the binary composition may include Sn(X)Ti(y)O2, wherein x+y=1, 0.85y0. In other embodiments of the present disclosure, the Sn compound includes a ternary composition including Sn(a)Ti(b)Zr(c)O2, wherein a is 0.25, b is 0.25 and c is 0.5. Certain embodiments of this disclosure include a method for the conversion of CO in an exhaust stream, including contacting an exhaust stream containing CO with the catalyst described above containing a Sn compound. In other embodiments, the exhaust stream includes hydrocarbons.
