摘要: Gold and nickel particles immobilized on alumina were prepared by the metal vapor synthesis anionic adsorption methods. The dispersion of metals was determined X-ray diffraction transmission electron microscopy. activity nanoparticles, tested in model catalytic reactions CCl4 addition to multiple bonds allyl isomerization allylbenzene, changes a wide range (from 1 3000 (mole product) Au)−1 h−1) is parallel chromatographically measured heats corresponding unsaturated substrates. heat hydrocarbons can serve as criterion for efficiency gold-containing catalyst olefin conversion.
