The　Au/Fe2O3　catalyst　was　prepared　by　co-precipitation,　deposition-precipitation,　and　modified　deposition-precipitation　methods　and　was　characterized　by　X-ray　diffraction,　X-ray　photoelectron　spectroscopy,　and　transmission　electron　microscopy.　The　catalyst　activity　for　the　water-gas　shift　(WGS)　reaction　was　discussed.　Under　strictly　controlled　conditions,　the　Au/Fe2O3　catalyst　prepared　by　modified　deposition-precipitation　displayed　higher　activity　for　the　WGS　reaction　than　that　prepared　by　co-precipitation　and　deposition-precipitation.　In　the　former　case,　the　CO　conversion　of　82.3%　was　obtained　with　a　feed　gas　of　10%　CO/N2　at　150　°C.　Wherein,　gold　particles　of　3-5　nm　were　highly　dispersed　on　the　surface　of　the　Fe2O3　support　that　existed　in　an　amorphous　and　crystalline　state.　A　relatively　strong　interaction　between　gold　particles　and　the　support　occurred,　which　was　beneficial　for　the　WGS　reaction.　©　2008　Dalian　Institute　of　Chemical　Physics,　the　Chinese　Academy　of　Sciences.
