Photocatalytic removal of soot: unravelling of the reaction mechanism by EPR and in situ FTIR spectroscopy.

Abstract

Photocatalytic soot oxidation is studied on P25 TiO(2) as an important model reaction for self-cleaning processes by means of electron paramagnetic resonance (EPR) and Fourier transform infrared (FTIR) spectroscopy. Contacting of carbon black with P25 leads on the one hand to a reduction of the local dioxygen concentration in the powder. On the other hand… (More)
