Al2O3-Ce0.3Zr0.7O2　and　3　wt%　BaO　doped　Al2O3-Ce0.3Zr　0.7O2　were　prepared　by　coprecipitation　and　the　supported　0.25　wt%　Pd　catalysts　were　compared　in　the　complete　oxidation　of　methanol.　The　work　dealt　with　a　combined　investigation　of　the　effect　of　adding　barium　on　the　characteristics　of　the　catalyst　and　on　its　catalytic　performance　of　methanol　oxidation.　The　results　demonstrate　that　more　active　sites　at　low　temperature　and　more　basic　sites　needed　for　deep　oxidation　of　methanol　are　formed　after　doping　barium.　©　2012　Elsevier　B.V.
