摘要：
Adsorption and photocatalytic reaction of 2-propanol over titanium(IV) oxide (TiO2) were studied by Fourier transform infrared spectroscopy (FTIR) using a photoacoustic (PA) technique. At first, the validity of the FTIR system using a home-made PA cell was confirmed by comparison with conventional transmission FTIR. The spectrum of TiO(2)with 2-propanol showed different propoxy peaks from those of gaseous 2-propanol as a result of chemisorption on TiO2. Finally, in situ FTIR observation of the photocatalytic oxidation of 2-propanol was carried out. Under ultraviolet irradiation, PA spectra changed due to complete oxidation of 2-propanol through acetone as an intermediate. (C) 2016 Elsevier B.V. All rights reserved.
