Immobilisation of Ferricinium Cation into ETS-10 by Ion Exchange under Microwave Irradiation
The microporous titanosilicate ETS-10 was subjected to three cycles of ferricinium ion ([(η5-C5H5)2Fe]+, Fc+) exchange by using aqueous solutions of ferricinium hexafluorophosphate and microwave-assisted heating. The resultant hybrid inorganic-organometallic (ETS-10/Fc+) 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, 29Si and 23Na 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.
