Core-shell ZrO2/SiO2 composite was prepared for HPLC support material with layer-by-layer self-assembly (LbL SA) technique. The composite with specific surface area of 172.5 m2/g consists of silica microsphere templates as core and zirconia nanometer particle layers as shell. The novel ZrO2/SiO2 composite can be a promising HPLC support compared with ZrO2 sphere because of its higher surface area.

Key words: HPLC, preparation, zirconia-based support material, surface area
