FTIR in situ - ethylene decomposition on TiO2

These data contain FTIR spectra recorded in FTIR spectrometer Nicolet iS50 coupled with High Temperature Chamber "The Praying Mantis". These spectra were measured for TiO2 irradiated by UV and under flowing of ethylene gas diluted in air. FTIR spectra were measured in situ during the photocatalytic process of ethylene decomposition. In order to identify the species, which were bounded to the titania surface upon the photocatalytic process, some spectra from the library database were added, such as: formic acid, formaldehyde and CO2.
