Реферат: The main question involved in this work concern with correct support choice at the step of catalyst design as it might influence catalytic performance due to metal-support interaction caused either by electronic state of metal or by specific interaction between solution compounds and support surface. Palladium catalysts supported on inorganic solids of various nature were tested in hydrogenation reactions of substituted olefins (cyclohexene and maleic acid) in aliphatic alcohols and water as solvents. According the XPS data no correlation between Pd electronic state and its specific catalytic activity was found. Irrespective to the content of water in aliphatic alcohol solvent specific catalytic activity of supported Pd in cyclohexene hydrogenation depend on support material nature. The trend of this change doesn’t agree with analogous trend in maleic acid hydrogenation. The structure sensitivity of the reactions occurs only after high-temperature reduction of Pd with H2 at 400°C
