Rhombohedrally　crystallized　three-dimensionally　ordered　macroporous　(3DOM)　La0.6SrO4CoO3　(LSCO)supported　Co3O4　(x　wt%　o(3)O(4)/3DOM　LSCO;　x=0,　2,　5,　8,　and　10)　were　prepared　using　the　in　situ　poly(methyl　methacrylate)-templating　strategy.　Physicochemical　properties　of　the　materials　were　characterized　by　means　of　numerous　analytical　techniques,　and　their　catalytic　activities　were　evaluated　for　the　combustion　of　toluene.　It　is　shown　that　the　x　wt%　Co3O4/3DOM　LSCO　samples　displayed　a　3DOM　architecture　and　a　high　surface　area　of　29-32　m(2)/g.　Among　the　x　wt%　Co3O4/3DOM　LSCO　samples,　the　8　wt%　Co3O4/3DOM　LSCO　sample　possessed　the　highest　adsorbed　oxygen　species　concentration　and　the　best　low-temperature　reducibility.　The　8　wt%　Co3O4/3DOM　LSCO　sample　showed　the　best　catalytic　performance　for　toluene　combustion　(the　temperatures　required　for　toluene　conversions　of　10,　50,　and　90%　were　158,　210,　and　227　degrees　C　at　a　space　velocity　of　20,000　mL/(gh),　respectively).　The　apparent　activation　energies　(43-58　kj/mol)　of　the　x　wt%　Co3O4/3DOM　LSCO　(x=0-10)　samples　were　lower　than　those　(59-67　kJ/mot)　of　the　8　wt%　Co3O4/bulk　LSCO　and　bulk　LSCO　samples.　It　is　concluded　that　the　excellent　catalytic　performance　of　8　wt%　Co3O4/3DOM　LSCO　was　associated　with　its　high　oxygen　adspecies　concentration,　good　low-temperature　reducibility,　and　strong　interaction　between　Co3O4　and　LSCO　as　well　as　high-quality　3DOM　structure.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
