Three-dimensionally　ordered　macroporous　(3DOM)　single-phase　rhombohedral　perovskite-type　oxide　LaMnO3　materials　with　nanovoid　skeletons　were　prepared　using　the　poly(methyl　methacrylate)-templating　methods　with　the　assistance　of　surfactant　(poly(ethylene　glycol)　(PEG)　or　triblock　copolymer　(Pluronic　P123)).　The　nature　of　surfactant　influenced　the　pore　structure　of　the　LaMnO3　sample.　The　use　of　PEG400　alone　led　to　a　3DOM-structured　LaMnO3　without　nanovoid　skeletons:　with　the　addition　of　PEG400　and　P123,　however,　one　could　prepare　LaMnO3　samples　with　high-quality　3DOM　structures,　nanovoid　skeletons,　and　high　surface　areas　(37-39　m(2)/g).　Under　the　conditions　of　toluene　concentration　=　1000　ppm,　toluene/O-2　molar　ratio　=　1:400,　and　space　velocity　=　20,000　mL/(g　h),　the　porous　LaMnO3　samples　were　superior　to　the　bulk　counterpart　in　catalytic　performance,　with　the　nanovoid-containing　3DOM-structured　LaMnO3　catalyst　performing　the　best　(the　temperatures　for　toluene　conversions　of　50%　and　90%　were　222-232　and　243-253　degrees　C,　respectively).　The　apparent　activation　energies　(57-62　kJ/mol)　over　the　3DOM-structured　LaMnO3　catalysts　were　much　lower　than　that　(97　kJ/mol)　over　the　bulk　LaMnO3　catalyst.　We　believe　that　the　excellent　performance　of　the　3D　macroporous　LaMnO3　materials　in　catalyzing　the　combustion　of　toluene　might　be　due　to　factors　such　as　large　surface　area,　high　oxygen　adspecies　concentration,　good　low-temperature　reducibility,　and　unique　nanovoid-containing　3DOM　structure　of　the　materials.　(C)　2011　Elsevier　Inc.　All　rights　reserved.
