Characterization of TiO2/SiO2 Based Stationary Phase for RP-HPLC

In this paper, we prepared a reversed-phase support by bonding octadecyltrichlorosilane onto TiO2/SiO2 particles, which were prepared by a layer-by-layer self-assembly technique and consists of micrometer-sized silica spheres as core and nanometer-sized titania particles as surface coating.
