Abstract

Provided are improved catalyst compositions for use in oxidizing carbon monoxide and methods of preparing these catalysts. The catalyst compositions are particularly useful at ambient temperatures. The catalyst compositions, prepared by a coprecipitation method, comprise an oxide of cobalt as the principal component with one or more metals selected from the group consisting of manganese (Mn), aluminum (Al), bismuth (Bi), cerium (Ce), chromium (Cr), copper (Cu), iron (Fe), lanthanum (La), magnesium (Mg), titanium (Ti), zinc (Zn), and zirconium (Zr).
