In situ IR spectroscopy data and effect of the operational parameters on the photocatalytic activity of N-doped TiO₂.

ABSTRACT: The TiO₂ photocatalyst doped with nitrogen was synthesized via a precipitation method and investigated in the oxidation of acetone vapor under UV (371 nm) and visible light (450 nm). The data were collected in a continuous-flow set-up equipped with a long-path IR gas cell for in situ analysis of oxidation products and evaluation of the photocatalytic activity. The IR spectra for inlet and outlet reaction mixtures and their change during the process are presented. A technique for quantitative analysis of initial substrate and oxidation product using collected IR spectra is described. The effects of main operational parameters, namely, outlet concentration of oxidizing substrate in the range of 0-25 μmol/L, humidity in the range of 10-85%, and surface density of photocataly
