“…This result resembles that of CO adsorption on K-covered Ni(1 1 1) [29,30] and suggests that an oxalate-type complex [OOC-COO] may be formed on the Cscovered surface. Both Cs and Ag are known to form stable, but different, oxalate crystal structures [31][32][33][34][35].…”

Temperature programmed desorption (TPD) and secondary ion mass spectrometry (SIMS) have been used to study the chemisorption propertieý of carbon monoxide on potassium predosed Pt.SIMS cluster ions (such as K , K 2 , KO+ and KCO+) were monitored to probe, K-CO interactions.Large changes in the SIMS yields are observed as the potassium coverage is varied.The SIMS results are correlated with previous work function change and TPD studies. Temperature programmed secondary ion mass spectrometry of potassium-containing ions indicates a local interaction between potassium and CO molecules.As typically observed on transition metal surfaces, two different CO TPD states are observed.The lower temperature state shifts to higher temperatures with increasing potassium coverage and to lower temperatures with increasing CO exposure.The high temperature CO state builds in with increasing potassium coverage and is accompanied by simultaneous potassium desorption.Evidence for the occurrence of both long-range (indirect) and short-range (direct) potassium effects on adsorbed CO is presented.

“…However, it has also been suggested that surface K creates a dipole moment in the opposite direction to that associated with CO adsorption, stabilizing the interaction of CO with the surface through electrostatic interactions (through-space interactions) with adsorbates [129,130,134]. It has also been hypothesized that K and CO interact primarily through ionic bonding [140], or that there is even intermixing of K and CO orbitals to form a chemical bond [141,142]. The long-range effect has likewise been attributed to both surface electronic and electrostatic effects [143,144].…”
