英文摘要	pt@ceo2 and pt@ce0.67zr0.33o2 prepared by microemulsion method were studied for water-gas shift reaction in pure syngas and sour syngas from 573 k to 773 k. both showed high catalytic activities in pure syngas with co conversion (x-co) nearly to equilibrium status at temperature above 723 k. and the side reaction of methanation was inhibited throughout the temperature range. pt@ce0.67zr0.33o2 showed lower x-co in pure syngas, but higher in sour syngas than pt@ceo2, indicating that the former is more resistant to h2s than the latter. although a decrease in x-co was observed in sour syngas relative to pure syngas, stability experiments carried out over pt@ce0.67zr0.33o2 indicated that the catalytic activity could be recovered after the removal of h2s.
