Carbon materials containing iron, cobalt ions have been prepared by a novel process based on the reaction of aluminum and dicholoroethane in liquid paraffin, modified with the chlorides of Fe (III), and Co (II), and the obtained xerogel designated as Fe/CTC-110 and Co/CTC-110. The resulting materials were deposited by micro plasma chemical vapor deposition (MPCVD) method at 800°C in inertmixed atmosphere (C2H2 and He). The obtained materials from this method were characterized by means of different techniques, such as X-ray fluorescence microscopy (XRFM), Xray diffraction (XRD), UV-vis spectroscopic studies and Dynamic light scattering analyses (DLS) for particle size determination and size distribution of the targeted samples. The cobalt and iron – carbon nanoparticles have been discussed, and the stability of the formed nanoparticles of these samples have been studied at different temperatures at the range from 18 to 70 °C. UV–visible spectroscopy has been carried out for determination of optical band and the nanoparticles size of the samples. Powder X-ray analysis (XRD) revealed the amorphous structure of these systems before deposition and crystallinity after deposition. Xray fluorescence microscopy (XRFM) studies revealed the homogeneous distribution of elements over the depth. Overall, the results of size of iron, cobalt- carbon nanoparticles have been compared through time-dependent absorption behavior and UV studies. The morphology of the samples has been studied by using scanning electron microscopy (SEM).
