Chapter 52: Comparison of Photocatalytic Activity of TiO2 Anatase Prepared by the Sol-Gel Technique and Chemical Vapour Deposition on Naphthalene in the Gas Phase

Popis výsledku v původním jazyce

In this study the gas phase photocatalytic oxidation of naphthalene in the presence of TiO(2)-based photocatalysts prepared by chemical vapor deposition (CVD) and the sol-gel method is examined. The level of naphthalene degradation was examined with FTIRspectroscopy; the identification of the products obtained was performed by GC-MS measurements. The kinetics of the photooxidation reaction of naphthalene in excess of oxygen was investigated. It was found that the kinetics of naphthalene oxidation follow a first-order law; the rate constants were determined by means of mathematical modeling. The photocatalytic activity of TiO(2)-based photocatalysts prepared by CVD as a gas phase method and the sol-gel technique as a liquid method are compared. The photocatalysts showed an excellent efficiency for naphthalene degradation in the presence of oxygen; a complete mineralization of the aromatic toxic compound to CO(2) and water was achieved.
