The Reactive Chemisorption of Carbon Dioxide at Mg(100) Surface

Abstract

<em>X-ray photoelectron and electron energy loss spectroscopic (XPS-EELS) studies reveal that the following species are present when a mixture of CO₂ and water vapour is exposed to the clean Mg(100) surface at 110K: CO_3(a), C_(a) CH_(a), OH_(a). The reactive chemisorptions of CO₂ and H₂O vapour coadsorbed on a Mg surface leads to the formation of CH bond. Increasing the temperature to 400 K shows the peaks in the C(1s) region of the spectrum disappears suggesting the CH containing species are not stable at 400K.</em>
