Abstract

The synthesis of mesoporous nanocrystalline TiO 2 films in a premixed (in vol %) 12.9/14.4/72.7 H 2/O 2/Ar flame doped with 0.1% titanium tetraisopropoxide [Ti(OC 3H 7) 4] was studied. Stabilization of the flame and deposition of TiO 2 nanoparticles were carried on the plane of a rotating disk. Spatial distributions of temperature and concentrations of major species in the flame were investigated. The applicability of the employed kinetic reaction scheme and the calculation method to the description of the structure of the investigated flame was tested. It was established that this method can be used to synthesize spherical crystalline nanoparticles of the anatase polymorphic form of TiO 2 with an average diameter of 12 nm and a narrow size distribution (σ = 1.45), which can be used in the production of solar cells and gas analyzer sensors.
