Abstract

We have studied polluting gases in tobacco smoke by investigating the phenomenon of capturing and photocatalysis effects of ZnO nanowire array (NWA). Capturing and photocatalysis reactions were continuously tracked by FTIR spectroscopy. The presence of ZnO improves the capture rate at room temperature, while the photocatalytic reactions can lead to a further reduction of the pollutants. MEMS-FTIR spectrometer operating in the Mid-Infra-Red appeared as a very promising tool for the online monitoring of air purification process.
