    Low-temperature CO oxidation over water tolerant Pt catalyst supported on Al-modified CeO2

    A series of xAl-(1-x)Ce oxides (x=0-0.20) were prepared as supports by the coprecipitation method. 1 wt% Pt was impregnated on the Al-modified Ce oxide supports, which were tested as catalysts for CO oxidation...
