Changes In The Electronic Structure Of Ni/TioX Composites As A Function Of Reduction Temperature, Hans Conrad Zur Loye, Angelica Stacy

Hans Conrad zur Loye

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. …
