摘要: Abstract The controlled surface reaction of an organometallic compound, such as tetrabutyl tin, with hydrogen covered rhodium particles supported on silica leads to a very well defined superficial species. These species are characterized by rhodium-tin bonds and contains butyl radicals still linked tin atoms. As the temperature thermal treatment is increased, progressively eliminated leading at last formation bulky alloy particles. presence these metallic induces increase not only in selectivity but also activity regarding hydrogenation carbonyl function unsaturated aldehyde citral.
