Abstract

Transition-metal catalysts are dispersed on high surface area oxide supports in order to obtain a large catalytic activity per metal atom. Many supports, such as SiO₂, and A1₂0₃, are considered to be inert; that is, these supports do not alter the intrinsic activity of the metal significantly but only serve to increase the surface area of the metal and prevent sintering. For some oxide supports, however, there is a strong interaction between the metal and the support. In particular, TiO₂, can affect the activity of the supported metal depending on the conditions under which the metal-titanium dioxide composite is prepared. It is our goal to learn how to control the chemistry of supported metals by modifying the support composition and the composite preparation temperature.
