In this investigation we synthesized NaX-Nanozeolite by hydrothermal crystallization conditions.These nanoparticles were prepared at different conditions in a temperature controlled shaker. Thesynthesized zeolites were characterized by instrumental analysis methods, such as X-raydiffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) andtransmission electron microscopy (...

The electrochemical properties of cytochrome c (cyt c) immobilized on multilayer nanozeolite-modified electrodes have been examined in aqueous and nonaqueous solutions. Layers of Linde type-L zeolites were assembled on indium tin oxide (ITO) glass electrodes followed by the adsorption of cyt c, primarily via electrostatic interactions, onto modified ITO electrodes. The heme protein displayed a ...

Zeolite–sepiolite inorganic nanoheterostructures have been hydrothermally synthesized by adding a dispersion of colloidal sepiolite to a solution able to produce a nanocrystalline zeolite (silicalite). The obtained product could be recovered in good yield by simple filtration only when the relative sepiolite concentration exceeded a threshold of 1.8 wt% in the synthesis mixture (amounting to 1:...
