Description
A low-pressure pulsed dc discharge in air has been used to study the mechanisms of the activation of an oxidative catalyst by plasma irradiation. Porous alumina has been employed as the catalyst. The oxidation of acetylene (C2H2) has been monitored measuring simultaneously the concentrations of CO and CO2 by infrared laser absorption spectroscopy. It was found, that the oxidation efficiency and the CO2/CO selectivity are greatly enhanced by the presence of the catalyst inside the plasma region and increase with the duty cycle ratio of the pulsed plasma
