Preparation of catalyst from natural montmorillonite mineral and its application in the synthesis of carbon nanosphere

In developed countries, nanoparticles derived from natural minerals and high-purity chemicals both are widely studied, while in developing countries like Mongolia, the minerals-based have more interest because of low production cost applicability domestic for their production. For synthesis mineral-based nanomaterials, it is important first to define chemical composition physical structure local possible processing route. We employed an environmentally friendly alkaline leaching procedure recover silica clay mineral at 90°C 24 hours. applied organic surfactant (CTAB) a simple coprecipitation approach form iron-doped nanoparticles. Consequently, we used as substrate catalyst carbon nanosphere 750 °C 1 hour argon acetylene gas atmosphere. As result, vast quantities superhydrophobic nanospheres (CNS) were obtained. The physicochemical properties nanosilica substrate, non-functionalized nanosphere, functionalized samples characterized using XRD, XRF, SEM, EDS, TEM, FTIR spectrometer. Iron-doped mineral-derived particles demonstrated high catalytic efficiency potential produce large amount value-added nanospheres. Superhydrophobic CNS can be variety applications, particularly drug delivery; however, use aqueous non-aqueous media, modified different oxidizers. changes hydrophobicity examined suggested oxidizing agents.
