“…The particle size can be evaluated by the height value of the AFM analysis. Because the height value of the AFM has a good resolution in comparison with the horizontal value [4,10]. As a result of AFM observation, it is found that Pd NPs have the average diameter of 2.6 nm with the standard deviation of 1.1 nm.…”

We have fabricated Pd nanoparticles (NPs) with clean surface and revealed the adsorption reaction of dimethyl sulfide (DMS) on Pd NPs/Ni(111) surface depending on the amount of deposited Pd NPs using in-situ X-ray Photoelectron Spectroscopy (XPS). As a result of XPS, DMS does not decompose on Ni(111) and bulk Pd surface. However, DMS dissociates into methanethiolate (MT; CH3S-) and atomic S on Pd NPs/Ni(111). It is found that the activity of Pd NPs surface is higher than that of bulk Pd surface.
