Abstract
DURING a study of the influence of pre-irradiation of a supported silver catalyst by γ-rays on conversion and yield in the oxidation of ethylene to ethylene oxide and CO2 and H2O, ESCA was employed to ascertain whether or not pre-irradiation altered the chemical composition of the silver catalyst surface. The influence of pre-irradiation on ethylene conversion and yield of ethylene oxide is reported elsewhere (J. J. Carberry, G. C. Kuczynski and E. Martinez, to be published); in this communication we wish to report changes in the surface chemical composition of the silver. We employed a Varian IEE-15 ESCA with an Mg source; K alpha energy line1.
