Abstract:In this study an easy access for modification of properties of porphyrin covered TiO2 electrodes by post-assembling metal insertion was investigated. Therefore a new type of phosphonic acid terminated porphyrin was synthesized and immobilized on mesoporous TiO2 electrodes by self-assembling. Surface concentrations in a range of 1.5–3.3 × 10-8 mol.cm-2, based on the geometric area, were obtained by two independent techniques, UV-vis and cyclic voltammetry. Co(II) , Zn(II) , Pd(II) and Mn(III) ions could be inse… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
