Catalysis is a branch of chemical kinetics of great industrial and commercial importance. Heterogeneous catalysts are certain particulate solids of high surface area (1-300 m2g_1) that increase the rates of attaining equilibria. This is achieved by the temporary attachment of reactant molecules by moderate chemical bonds to active sites on their surfaces. Catalysts themselves are not consumed during the process, although their activity is eventually lost by surface degradation. Over 90% of the world's manufactured chemicals involve catalysis at one or more stages. The market is about £7 x 109 per annum, with £200 return on each pound spent on a catalyst.
