Photocatalyst activation in a pulsed low pressure discharge

Résumé

The effect of combining plasma and photocatalyst for Volatile Organic Compounds (VOC) removal was investigated in a pulsed low-pressure dc discharge. The photocatalyst was TiO2 while the VOC was acetylene (1000 ppm) diluted in dry air. The temporal evolution of C2H2 concentration was measured by Tunable Diode Laser Absorption Spectroscopy (TDLAS) in the mid-infrared region during the plasma pulse (one second). The contribution of external ultraviolet radiation and plasma exposure were quantified, both with and without a photocatalyst. The synergetic effect was clearly demonstrated.
