- Abstract
- This focussed review is an update concerning highly active surface species moving between different solids (the 'spillover' phenomenon). Initially, this specifically concerned the reactivity of solids (e.g. nucleus formation in the reduction of oxides to metals). More surprising and more important have been consequences concerning heterogeneous catalysis. Spillover hydrogen, H-so, and spillover oxygen, O-so, create active sites during catalytic processes. This leads to modifications of activity and selectivity in the treatment of petroleum fractions and in the selective oxidation of hydrocarbons in petrochemistry (by H-so, or O-so, respectively). For example, in hydrodesulfurization, H-so from a physically separated catalyst bed increases the activity of MoS2. O-so leads to a reconstruction of the surface of MoO3 and higher selectivity in oxidation. This opens completely new perspectives for the fundamental understanding of catalysis.
