Реферат: It is found for the gas-phase hydrogenation of vinylacetylene that supported palladium shows an approximately constant specific catalytic activity (turnover number TON) over a wide range of particle sizes, namely, from 40 to 180 Å, regardless of the nature of the support (silica or γ-alumina). With a decreasing in the size of the palladium particles from 40 to 10 Å the specific activity (TON) falls by one order of magnitude, a positive shift of the Pd 3d5/2level by 0.6 eV being observed. The low specific activity of highly dispersed palladium is caused by a stronger chemisorption of vinylacetylene on small electron-deficient clusters compared with large particles.
