Abstract:
A study has been made of the state of the components and the catalytic properties of (Ni plus Ti)/SiO2 obtained by decomposition of anchored Ni and Ti complexes. According to the results obtained in chemisorption measurements and electron microscopic examination, these catalysts contain nickel particles smaller than 10 Angstrom and also surface Ti**n** plus ions (n equals 2-3). The activity in hydrogenation of CO and the selectivity in forming higher hydrocarbons are considerably higher for the (Ni plus Ti)/SiO2 and Ni/TiO2 in comparison with Ni/SiO2; this difference can be attributed to interaction of a certain fraction of the nickel atoms with titanium ions, forming Ni-Ti**n** plus bonds. Preoxidation breaks these bonds, and the activity drops off sharply.
