Abstract: Chemisorption properties of thin films of Pd evaporated onto Nb recrystallized-foil surface have been studied by temperature-programmed desorption (TPD) and by measurement of the work function changes (WFC) at room temperature. TPD results indicate two states of CO adsorbed in dependence on the thickness of the palladium layer. The low temperature state (330 K) occurs at low Pd coverages (about one monolayer). Second state, occurring at slightly higher temperature (370 K), is attributed to bulk Pd. WFC data sh… Show more

“…Many research groups, especially Goodman and coworkers, have performed systematic TPD studies of CO desorption from a wide range of MBS structures [7,[11][12][13][113][114][115][116][117][118][119][120]. The experimental results from these studies clearly indicated that the desorption temperature of CO from the bimetallic surfaces is different from that of parent metals, and that the change in the desorption temperature is related to the modification of the electronic structures due to bimetallic formation.…”

“…Kitchin et al [30] have compared peak desorption temperatures of CO from many MBS systems from the literature [7,[11][12][13][113][114][115][116][117][118][119][120] and estimated the shift in peak desorption temperature with respect to desorption from the pure overlayer metal. DFT calculations were performed for each bimetallic surface to determine the change in the surface d-band center as compared to the pure metal.…”
