1-D nanostructures, such as nanowires and nanotubes, have been extensively studied due to their potentials as building blocks for fabricating electronic, magnetic, electrooptic, and electrochemical nanodevices. Especially, wide-bandgap semiconductor nanowires and nanorods including ZnO and SnO2 were reported significantly. As for their synthetic routes, a carbothermal reduction process has been...

Titanium carbide (TiC) is an important engineering material and has found widespread applications. Currently, TiC is typically synthesized through carbothermal reduction, requiring a high temperature (ca. 1700-2300 °C) and long reaction time (ca. 10-20 h), which is not eco-friendly. During a conventional reaction path, anatase TiO₂ (A-TiO₂) was first converted to rutile TiO₂ (R-TiO₂), which was...

Carbothermal reduction is among the oldest chemical processes, commonly used in the production of metals from the corresponding metal oxides or ores (e.g., iron from iron oxides). By using carbon as a reducing agent, decomposition of metal oxides at temperatures much lower than their typical decomposition temperatures can occur. However, a detailed fundamental understanding of such a reaction p...

A new approach to the generation of nanoparticle arrays in periodic as well as non-periodic fashions has been discovered based on reduction of oxidized nanoscroll/nanoribbon precursors in the transmission electron microscope (carbothermal reduction) or by hydrogen annealing. Arrays consisting of nickel arsenide nanoparticles of size 3-4 nm have been generated.

sn02 nanowires with diameters of 30 — 200 nm have been synthesized by using carbothermalprocess via a thick film of tin dioxide and carbon powder precursor. the nanowires werecharacterized by x-ray power diffraction (xrd), scanning electron microscopy (sem),transmission electron microscopy (tem) and selected area electron diffraction (saed).the gas sensing characteristic of nanowires toward eth...

Novel silicon carbide nanostructures, beaded nanochains, are prepared from the carbothermal reduction of a carbonaceous silica xerogel with cetyltrimethylammonium bromide and lanthanum nitrate as additives. The nanochains consist of a stem with a diameter of about 50 nm and uniform beads with diameters of 100–200 nm. It is demonstrated that the tensile strength of an epoxy composite filled with...

The influence of magnesium content on the mechanosynthesis of ZrB2–SiC–ZrC composite in Mg/ZrSiO4/B2O3/C mixture was investigated. Thermodynamic evaluations revealed that the amount of Mg played a main role, thereby; the overall reaction enthalpy and adiabatic temperature (Tad) changed by variation of magnesium content. According to differential thermal analysis (DTA) results, after 45min milli...

Electrospinning has emerged as a facile technology for the synthesis of ultrafine fibers and even nanofibers of various materials. While carbon nanofibers have been extensively investigated, there have also been studies reported on metal oxide and metal carbide fibers. Yet, comparative studies, especially following the same general synthesis approach, are lacking. In our comprehensive study, we...

During the synthesis of SiC, Si3N 4 and sialon whiskers by carbothermal reduction of SiO 2, a localized formation of amorphous phases or Si2N20 powders was observed beneath these whiskers. Because these whiskers were formed by the vapour/solid mechanism, the controlling gas phase was of primary importance to obtain whiskers of tailored morphology and chemistry. To elucidate the effect of the ga...
