The paper presents the synthesis and characterization of highly dispersed titania on the surface of fiberglass material. Scanning electron microscopy and X-ray digital 3D-microtomography showed that each support fiber was uniformly coated by modifying component. The layer of titania consisted of anatase particles of 18 nm, an average pore size was 3.1 nm. The prepared material revealed a catalytic activity in n-heptane cracking, deep and partial oxidation. The major products of n-heptane conversion at 300–400 °C in the presence of oxygen were ketones with a carbon number of 3–4. Above 500 °C, the deep oxidation increased dramatically with a simultaneous appearance of α-olefins.
