    • Novel Synthesis of SiC-SiO2 Nanotubes from Cinachyrella sp. and Its Improvement of the Corrosion Resistance of Low Carbon Steel in 3.5% NaCl Water Solution

    Coat synthesis of silicon carbide and composites of Si derivatives is a challenge for high-quality thin film applications, including corrosion resistance industries. A novel fabrication process of silicon carbide-silicon dioxide nanotube composites (SCDNTs) was developed by a solid reaction of silicon-carbon (marine sponge Cinachyrella sp.) resources. Trimetallic catalyst (Fe/Ni/Zr) supported on different Al2O3 media with heating in an argon flow was used to prepare SCDNTs composite. A higher crystallinity degree of the nanocomposites is attained at a heating temperature of 1200 °C as a suitable starting temperature to have a reasonable degree of crystallinity. XRD analysis of the prepared composite showed the presence of polycrystalline silicon dioxide and two phases of silicon car...
