The reactivity of titanium–vanadium containing groups in the synthesis of two-component monolayers on silica surfaces

Abstract

The coating of silica surfaces with two-component VOCl 3 and TiCl 4 monolayers was studied with respect to the composition of the products and the kinetics of interaction. The titanium and vanadium-containing groups were found to be able to replace each other equivalently. Surface sites were found to determine reactivity, as were lateral interactions in the monolayer. The results found the presence of two kinds of active center; with the estimated ratio of such groups correlating with data from chemical analyses of the concentrations of groups covalently linked to the surface by different numbers of bonds.
