Abstract: The surface properties of zirconia-based supports,ZrO2/SiO2 and ZrO2,were compared.ZrO2/SiO2 prepared by layer-by-layer self-assembly(LbL SA) technique showed more favorable characteristics for HPLC applications compared with ZrO2 prepared by modified oil-emulsion method.The specific surface area and pore volume of ZrO2/SiO2 were about 18 and 20 times of those of ZrO2 respectively.The pore of ZrO2/SiO2 support was ideal cylindrical shape,but ZrO2 support had some \!ink bottle\" shaped-pores which was unfavorable for HPLC separations.Pore size distribution of ZrO2/SiO2 supports was more uniform than that of ZrO2 supports.

Key words: Zirconia-based HPLC supports, Molecular self-assembly technique, Surface property, ZrO2/SiO2, ZrO2
