Description

The interaction of Au and Pd in bimetallic systems is important in a number of areas of technology, especially catalysis. In order to investigate the segregation behaviour in such systems, the interaction of Pd and Au was investigated by surface science methods. In two separate sets of experiments, Au was deposited onto a Pd(111) single crystal, and Pd and Au were sequentially deposited onto TiO2(110), all in ultra-high vacuum using metal vapour deposition.

The following data are provided.
Au4f/Pd3d XPS peak area ratio vs annealing temperature for thick and thin films of Au on Pd(111).
Initial sticking probability of CO at 393 K after annealing a Au dosed (50 s) Pd (111) surface at increasing temperatures for 300 s.
Raw XPS (x-ray photoelectron spectroscopy) data plots the binding energy (eV) vs counts per second (arbitrary units) along the x and y-axis respectively. The XPS data is in a three-column format – the first column of each result shows the raw data (the counts per second, CPS), the second column shows the background applied to the raw data in order to account for any noise in the spectra. The third column shows the resulting value when the background is subtracted from the raw data.
LEIS (low energy ion scattering) measurements giving the energy, in electron volts (eV) across the x-axis and counts (arbitrary units) along the y-axis. LEIS peak heights were taken using a linear background. The XPS data plots the binding energy (eV) vs counts per second (arbitrary units) along the x and y-axis respectively. The XPS data is in a three-column format – the first column of each result shows the raw data (the counts per second, CPS), the second column shows the background applied to the raw data in order to account for any noise in the spectra. The third column shows the resulting value when the background is subtracted from the raw data.

Research result based upon these data are published at http://dx.doi.org/10.1016/j.susc.2016.10.005
