Abstract

Small metal particles dispersed on inorganic oxides are among the most important heterogeneous catalysts. While the primary function of the oxide support is to increase the metal surface area, these supports can cause pronounced changes in the catalytic and chemisorption properties of the metal. In particular, metals supported on TiO₂, have attracted attention due to the observation that activity and selectivity for Fischer-Tropsch synthesis can be altered, depending on the temperature a t which the metal Ti0₂ composite is reduced. Furthermore, H₂ and CO chemisorption are suppressed for composites reduced at higher temperatures. In this paper, we show that the stoichiometry of the TiO_x, support has a large influence on the surface chemistry of the metal.
