Surface structure of K/Pd(100) and the effect of H coadsorption: Density functional theory calculations

In situ study of metal leaching from Pd/Al2O3 induced by K2CO3

“…Subsequently, Burchhardt et al employed low energy electron diffraction (LEED) to measure the adsorption of K on the Pd(100) surface, found a Pd-K distance of 2.13 Å, 46 which was supported later by DFT calculations. 47 The data provided by these studies agree well with two of the fitted shells (O at 2.71 Å, and Pd at 2.30 Å), suggesting that K is adsorbed all over the catalyst (on both the Al 2 O 3 and Pd). The nature of the remaining two shells (Pd at 3.25 Å, and C at 1.82 Å) is difficult to identify at this juncture.…”
