Three-dimensionally　ordered　macro-/mesoporous　silica　(3DOM　SiO2)-supported　manganese　oxide　and　gold　nanocatalysts　(yAu/zMnO(x)/3DOM　SiO2,　y　=O-O.95　wt%;　z　=　2.7-15.4　wt%　(weight　percentage　of　Mn2O3))　were　prepared　using　the　polymethyl　methacrylate-templating,　incipient　wetness　impregnation,　and　polyvinyl　alcohol-protected　reduction　methods,　respectively.　It　is　shown　that　the　yAu/zMnOx/3DOM　SiO2　samples　displayed　a　high-quality　3DOM　architecture　with　macropores　(180-200　nm　in　diameter)　and　mesopores　(4-6　nm　in　diameter)　and　a　surface　area　of　220-318　m(2)/g.　MnOx　nanoparticles　(NPs)　with　a　size　of　18.7-25.7　nm　were　dispersed　on　the　surface　of　3DOM　SiO2,　and　Au　NPs　with　a　size　of　3.6-3.8　nm　were　uniformly　dispersed　on　the　surface　of　zMnO(x)/3DOM　SiO2.　The　0.93Au/11.2MnO(x)/3DOM　SiO2　sample　performed　the　best　(the　temperature　required　for　achieving　a　90%　toluene　conversion　was　255　degrees　C　at　space　velocity　=　20,000　mL/(g　h))　for　toluene　oxidation.　It　is　concluded　that　the　higher　oxygen　adspecies　concentration,　better　low-temperature　reducibility,　and　stronger　interaction　between　Au　and　MnOx　NPs　as　well　as　the　unique　bimodal　porous　structure　were　responsible　for　the　good　catalytic　performance　of　0.93Au/11.2MnO(x)/3DOM　SiO2.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
