Metal particles Oxide supports Surface organometallic chemistry... 

In this review, we will specifically discuss the similarities and the differences between the chemistry on surfaces and molecular chemistry. In Sect. 2, we will first describe how to generate well-dispersed monoatomic transition metal systems on oxide supports and understand their reactivity. Then, the chemistry of metal surfaces, their modification and the impact on their reactivity will be discussed in Sect. 3. Finally, in Sect. 4, molecular chemistry and surface organometallic chemistry will be compared. 

It is first necessary to distinguish the surface organometallic chemistry on metals and on oxides since one deals with a large ensemble of metals, while the others generate dispersed metal atoms attached covalently onto the support. 

In contrast to supported homogeneous catalysis, surface organometallic chemistry (SOMC) uses an inorganic oxide (ExOy) as a solid ligand, on which the metal is directly attached by at least a bond with a surface atom, usually an oxygen, through a M-OE bond.
