C_2H_4 Decomposition Behavior of a Non-Thermal Plasma Discharge-Photocatalyst System for an Air Purifying Device

This study was conducted to examine how ethylene decomposes with a non thermal plasma discharge (NTPD)-photocatalyst system. The experimental study was carried out with variables of space velocity (SV), humidity and an input power to investigate the ethylene oxidation behavior in the system. The luminescence in the catalyst coated substrate, C_2H_4 decomposition, and the power factor behavior of the system were examined. As a result, the luminescence phenomenon was able to decompose C_2H_4 by activation of photocatalyst instead of UV-radiation, and there was a proportional relation between the humidity and decomposition as well as between the power factor (PF) and UV intensity of the plasma-photocatalyst. In addition there was an optimum SV for the decomposition of C_2H_4.
