Immobilisation of Ferricinium Cation into ETS-10 by Ion Exchange under Microwave Irradiation

abstract

The microporous titanosilicate ETS-10 was subjected to three cycles of ferricinium ion ([(eta(5)-C5H5)(2)Fe](+), Fc(+)) exchange by using aqueous solutions of ferricinium hexafuorophosphate and microwave-assisted heating. The resultant hybrid inorganic-organometallic (ETS-10/Fe+) materials were characterised by elemental analysis, ICP-AES, FTIR and Raman spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance (DR) UV-Vis, Si-29 and Na-23 solid-state NMR. The results support the successful inclusion of Fc(+) in the pores of the inorganic host by ion exchange of extra-framework sodium and potassium ions.
