Grafting of diazonium salts on oxides surface: formation of aryl-O bonds on iron oxide nanoparticles
Résumé
Combining ab initio modeling and 57 Fe Mössbauer spectrometry, we characterized the nature of the chemical linkage of aminoalkyl arenediazonium salt on the surface of iron oxide nanoparticles. We established that it is built through a metal-oxygen-carbon bonding and not a metal-carbon one, as usually suggested and commonly observed in previously studied metal-or carbon-based surfaces.
