Studies of Surface Reactions Using Electron-Adsorbate Interaction Techniques.

The report discusses a completed study of the adsorption and decomposition of CO on a Pt(111) surface by Auger electron spectrometric (AES) and electron-induced desorption (EID) techniques. CO was found to adsorb on the clean surface by first-order Langmuirian kinetics. Adsorbed carbon produced by electron-induced decomposition of adsorbed CO poisoned the adsorption process. The kinetics of this process have been determined from AES and EID studies. A continuing study of gas adsorption on Fe(110) is also discussed. The experimental techniques being used, plan of attack and results to date are presented. (Modified author abstract)
