Ligand exchange surface complex model

The central ion of a mineral surface (in this case we take for example the surface of a Fe(lll) oxide and S-OH corresponds to =Fe-OH) acts as Lewis acid and exchanges its stuctural OH against other ligands (ligand exchange). Table 2.1 lists the most important adsorption (= surface complex formation) equilibria. The following criteria are characteristic for all surface complexation models (Dzombak and Morel, 1990.)... [Pg.15]

Figure 6.16 Proposed chemical interaction of Pt complexes with an alumina surface, which involves surface-ligand exchange of either surface OH for Cl ligands (model B1) or Cl ligands from the CPA complex for surface hydroxyls (model B2). (From Shelimov, B., Lambert, J.-F., Che, M., and Didillon, B., J. Mol. Catal. 158, 2000, 91.)...
