A practical, inexpensive and scalable synthesis method, based on the Fe 2+ exchange of two commercial zeolites (i.e. Na-A and Na-X) followed by reductive thermal treatment at 1023 K, allowed obtaining nanocomposites where Fe nanoparticles are dispersed within an agglutinitic glassy matrix stemming from the amorphization of the zeolite precursor. The materials were characterized by means of atomic absorption spectrometry; X-ray powder diffraction followed by Rietveld analysis; transmission electron microscopy; N 2 adsorption/desorption isotherms at 77 K; measurements of grain size distribution; magnetic properties measurements; broadband dielectric spectroscopy and DC conductivity measurements.
