Effects of adding super fine powder ZrO2 on the structure of the support, surface oxygen property and oxidizative activity of Pd/Al2O3 catalyst were investigated by XRD, DTA, TPD-MS and flowing reaction method. It was shown that ZrO2 would prevent the phase transformation (α-Al2O3) of Al2O3 effectively, and promote the ability of storing oxygen and activity of surface adsorption oxygen of the catalyst. Thus, it increased thermal stability, oxidative ability and adaptive ability of catalyst under a lean O2 condition.
