Received Date: 18 November 1995

In this letter the catalytic properties of zirconia in CO hydrogenation are presented.The catalylsts were prepared under different conditions.Some of them have good activity and selectivity for olefins,especially for isobutcne.The catalysts were characterized by EPR technique.The results showed that all good catalysts give an EPR signal at g=1.974 which canbe assigned to Zr³⁺ on the surface of ZrO₂.The probable active center of ZrO₂ catalyst was suggested.
