Three-dimensionally　ordered　macroporous　(3DOM)　Fe2O3　and　0.48-1.95　wt%　Au/3DOM　Fe2O3　catalysts　were　prepared　using　the　poly(methyl　methacrylate)-templating　and　polyvinyl　alcohol-protected　reduction　methods,　respectively.　It　is　found　that　the　porous　catalysts　with　a　surface　area　of　45-46　m(2)/g　were　of　a　rhombohedral　alpha-Fe2O3　crystal　structure,　and　Au　nanoparticles　(NPs)　with　a　size　of　4-6　nm　were　well　dispersed　on　the3DOM　Fe2O3　surface.　The　1.95Au/3DOM　Fe2O3　sample　possessed　the　best　low-temperature　reducibility　and　showed　the　highest　catalytic　activity　(T-50%　=　162　degrees　C　and　T-90%　=　204　degrees　C　at　SV　=　20,000　mL/(g　h))　for　toluene　oxidation,　which　was　associated　with　its　well-dispersed　and　small　sized　Au　NPs,　good　low-temperature　reducibility,　and　strong　interaction　between　Au　NPs　and　3DOM　Fe2O3.
