This　work　aimed　at　exploring　a　new　kind　of　purification　catalysts　for　fuel　ethanol　engine　exhaust.　Platinum　loaded　on　Ce0.5Zr0.5O2　was　prepared　by　impregnation　method　and　characterized　by　X-ray　diffraction,　Brunner-Emmet-Teller　measurements　(BET),　temperature-programmed　reduction　of　hydrogen,　scanning　electron　microscope,　and　X-ray　photoelectron　spectra.　The　three-way　catalyst　platinum/ceria-zirconia/fw　is　prepared　with　the　paste　ball　mill　coating　technique.　And　the　catalytic　performance　is　evaluated　under　simulated　fuel　ethanol　engine　exhaust　gas　condition.　The　catalysts　not　only　show　excellent　low-temperature　performances　and　several-way　catalytic　activities　for　carbon　monoxide,　hydrocarbons,　nitrogen　oxides,　and　acetaldehyde　but　also　have　better　high-temperature　resistance.　The　addition　of　sulfur　dioxide　to　feedstream　degrades　the　performances　of　the　catalysts.
