Three-dimensionally　ordered　macroporous　(3DOM)　La0.6Sr0.4MnO3　(LSMO)　and　its　supported　gold　(xAu/LSMO,　x　=　3.4-7.9　wt%)　catalysts　were　prepared　using　the　polymethyl　methacrylate-templating　and　gas-bubble-assisted　polyvinyl　alcohol-protected　reduction　methods,　respectively.　There　were　good　correlations　of　surface-adsorbed　oxygen　species　concentration　and　low-temperature　reducibility　with　the　catalytic　activity　of　the　sample　for　CO　and　toluene　oxidation.　Among　the　LSMO　and　xAu/LSMO　samples,　6.4Au/LSMO　performed　the　best,　giving　T-50%　and　T-90%　values　of　-19　and　3　degrees　C　for　CO　oxidation　and　150　and　170　degrees　C　for　toluene　oxidation,　respectively.　The　apparent　activation　energies　(31-32　and　44-48　kJ/mol)　obtained　over　xAu/LSMO　were　much　lower　than　those　(45　and　59　kJ/mol)　obtained　over　LSMO　for　the　oxidation　of　CO　and　toluene,　respectively.　It　is　concluded　that　higher　oxygen　adspecies　concentration,　better　low-temperature　reducibility,　and　strong　interaction　between　Au　and　LSMO　are　responsible　for　the　excellent　catalytic　performance　of　6.4Au/LSMO.　(C)　2013　Elsevier　Inc.　All　rights　reserved.
