Ligand-to-metal charge transferOxalate-adsorbed TiO2 shows visible activity for the oxidation of ranitidine, although neither oxalate nor pure TiO2 alone absorbs visible light. The formation of an oxalate-TiO2 complex facilitates electron transfer from oxalate to the TiO2 conduction band (CB) (i.e....
Coordinative bonds in metal organic frameworks are most of the time well known because identical to those typical of simple complexes and often understood within the ligand field theory [4]. On the other hand, it is the regio-selectivity in multi-dentate organic linkers to be more intriguing an...
Therefore, CR1 provides information on the cleanness of a metal oxide surface and also indicates that at pH values above (below) CR1 the solid surface is negatively (positively) charged. CR3 depends on the nucleation of the metal hydroxide on the solid surface. If full coverage occurs then ...

In the soil solution an Al-oxalate complex induced a substantial decrease in oxalate adsorption when the pH fell below 4.5. No such effect was found in the soil-fulvate system. Adsorption constants obtained from binary systems (oxide-ligand) were used to model adsorption and competition in the ...
Ligand reactionAdsorption siteChemical modelBinary systemThe adsorption of oxalate and fulvate and the competition for surface-adsorption sites between SO 4 2– -oxalate and SO 4 2– -fulvate on goethite and on a soil material from a podzol B horizon were studied in batch titration experiments. ...
