Study of the Mechanism of Formation of Photoaccumulating Titania-Based Heterooxide Composites Using IR Spectroscopy
Abstract
The IR spectroscopic and photocatalytic studies of thin-film heterooxide composites TiO2-V2O5 obtained by codeposition of TiO2 and V2O5 colloids, chemical deposition of V2O5 shell over TiO2 particles, and thermal decomposition of ammonium vanadate in the presence of TiO2 particles have shown that the disordered V2O5 phase produced via pyrolytic synthetic route forms close heterocontacts with titania particles thus facilitating charge separation, while simultaneously ensuring favorable conditions for accumulation of the photoinduced charges.
