Abstract

We examine the adsorption, desorption and dissociation of CO//2 and formic acid on clean Pd(100) surfaces by Auger electron, electron energy loss and thermal desorption spectroscopies. We found that CO//2 adsorbs molecularly on a Pd(100) face at 110 K accompanied by the appearance of a loss feature at 14 ev. Desorption resulted only in one peak; T//p equals 142 K. No dissociation of CO//2 was observed even at higher adsorption temperatures. Formic acid dissociates on Pd(100) to adsorbed hydrogen and formate even at 110 K. At higher exposures chemisorbed and condensed HCOOH were also detected. The formate species started decomposing above 230 K producing desorbed CO//2 and adsorbed hydrogen.
