Three-dimensionally　(3D)　ordered　and　wormhole-like　mesoporous　iron　oxides　(denoted　as　Fe-KIT6　and　Fe-CA)　were　respectively　prepared　by　adopting　the　3D　ordered　mesoporous　silica　KIT-6-templating　and　modified　citric　acid-complexing　strategies,　and　characterized　by　a　number　of　analytical　techniques.　It　is　shown　that　the　Fe-KIT6-400　and　Fe-CA-400　catalysts　derived　after　400　degrees　C-calcination　possessed　high　surface　areas　(113-165　m(2)/g),　high　surface　adsorbed　oxygen　concentrations,　and　good　low-temperature　reducibility,　giving　90%　conversion　below　189　and　208　degrees　C　for　acetone　and　methanol　oxidation　at　20,000　mL/(g　h),　respectively.　It　is　believed　that　the　good　catalytic　performance　of　Fe-CA-400　and　Fe-KIT6-400　was　related　to　factors　such　as　higher　surface　area　and　oxygen　adspecies　concentration,　better　low-temperature　reducibility,　and　3D　mesoporous　architecture.　(C)　2010　Elsevier　B.V.　All　rights　reserved.
