摘要：
Sol-gel synthesis of mesoporous titania-silicas with the structure related to Type MCM-41 is carried out. The method of nitrogen adsorption has established influence of fluoride-anion on the adsorptive and catalytic properties of titania-silica. The pore structure in titania-silica is in the form of an hexagonal array of uniform tubular channels. Asymptotic increase in a specific surface area of titania-silica catalyst with growth of F/Si ratio is shown. Both silicas and titano-silicas showed catalytic activity in the reaction of isomerization of a-pinene epoxide. The largest activity (100% conversion) and selectivity for campholenic aldehyde (57%) was shown by titanosilicate synthesized at Ti/Si = 25/75 and F/Si = 0.4.
