摘要
Surface modification of mesoporous nanocrystalline TiO2 films with carboxymethyl-p-cyclodextrin (CMBCD) improves the adsorption of typically non anchoring species, such as bis(4-bromophenylterpyridine)iron(II), by means of host-guest interactions. Such host-guest strategy allows the exploitation of the photochemical properties of the TiO2 surfaces for the selective photodegradation of guest organic species. (c) 2006 Elsevier B.V.
