Literature data on palladium clusters obtained by the interaction of Pd(II) compounds in solutions with hydrogen are summarized and analyzed. The conclusion is drawn on the influence of ligands and reduction conditions on the polynuclearity of clusters and on the autocatalytic nature of their formation. Palladium clusters become active in the selective hydrogenation of alkynes and dienes only after...
Using the DFT–PBE method in the scalar relativistic approximation, the mechanisms of the two main pathways of propionic acid deoxygenation on the rough and flat (111) palladium surfaces have been studied. According to the calculations, in the decarboxylation mechanism on rough and flat surfaces, the formation of the following intermediates is preferable: C2H5COO, C2H4COO, and C2H4. For the second...
