Abstract :
Plasma pretreatment has been shown to enhance the efficiency of catalysts in a number of applications. In this study a nonthermal helium plasma was used for catalyst activation. The CO oxidation activity of alumina supported Au and Pd catalysts was monitored using gas chromatograph before and after plasma treatment. Catalysts were prepared by incipient wetness impregnation of Au and Pd salts on alumina.
