These include trends of reactivity and bonding across the periodic table; the observation that rough surfaces and defect sites have high reaction rates and more strongly bind the adsorbates; the reaction and chemisorption induced restructuring of metal surfaces; and the presence of a strong

In a few cases, more detailed mechanistic proposals have been advanced, but they remain modest in scope compared to the detailed mechanisms that have been developed in molecular organic chemistry

A convincing case is provided that the site densities are low and very often mononuclear rather than ensembles of two or more contiguous atoms. The mechanisms of reaction are then due to the interconversion of various transient intermediates as ligands of these mononuclear centres,

Proton attachment to the zeolite lattice causes a weakening of neighbouring Si-O and Al-O bonds. The effective increase in volume of the bridging oxygen atom causes a local deformation, that changes the strength

With the help of knowledge on methane coupling and butane oxidation, sites needed to activate and oxygenate molecules are proposed for alkanes.
