“…Nanomaterial synthesis is widely realized through non-plasma related methods, like chemical vapor deposition (CVD) [26][27][28], solvothermal routes [29][30][31], sol-gel methods [32][33][34], laser ablation [35][36][37], etc. Fine quality products could be obtained when the starting materials and processes were properly chosen and controlled by non-plasma methods.…”

Plasma technology has been widely applied in the ozone production, material modification, gas/water cleaning, etc. Various nanomaterials were produced by thermal plasma technology. However, the high temperature process and low uniformity products limit their application for the high value added chemicals synthesis, for example the functional materials or the temperature sensitive materials. Microplasma has attracted significant attentions from various fields owing to its unique characteristics, like the highpressure operation, non-equilibrium chemistry, continuous-flow, microscale geometry and self-organization phenomenon. Its application on the functional nanomaterial synthesis was elaborately discussed in this review paper. Firstly, the main physical parameters were reviewed, which include the electron temperature, electron energy distribution function, electron density and the gas temperature. Then four representative microplasma configurations were categorized, and the proper selection of configuration was summarized in light of different conditions. Finally the synthesis, mechanism and application of some typical nanomaterials were introduced. Plasma Chem Plasma Process (2015) 35:925-962

“…Because of their excellent properties carbon fibers have been applied for microwave absorbing material, lithium ion battery [4,10,11], capacitors [12], and biosensors [13,14]. Since 1960s, chemical vapor deposition (CVD) has been investigated to synthesize carbon fibers with three kinds of morphologies: linear carbon fibers [2,15], helical carbon fibers [15,16], and multi-branched carbon fibers (MBCFs) [12,17,18]. However, the synthesis of MBCFs still faces many challenges including low yield, uncontrollable irregular branches and debatable growth mechanism.…”

Carbon fibers with different morphologies are obtained using different cupric solution precursors (e.g., cupric sulfate, cupric nitrate, and cupric chloride) at various temperatures. The morphology of carbon fibers depends on the type of catalyst precursor and reaction temperature but not the concentration of the precursor solution. For example, cupric chloride solution is a desirable catalyst precursor for the growth of carbon fibers with multi-branches at 450 °C. However, a mixture of carbon sheets and linear fibers forms at 300-350 °C. The splitting mode can be used to explain the formation of carbon fibers with different morphologies at various reaction temperatures.

Nanotechnology V 1505Morphology-Controllable CVD Synthesis of Carbon Nanomaterials on an Alkali-Element-Doped Cu Catalyst. -Carbon nanomaterials are prepared by c hemical vapor deposition using an acetylene/NH3/N2 flow in the presence of an alkali metal-doped Cu catalyst (synthesized by combustion of a mixture of Cu(NO3)2, NaNO3, Mg(NO3)2, and citric acid at 500°C). By controlling the reaction temperature, various products such as multibranched carbon nanotubes, carbon nanotubes filled with Cu nanocones at the tips (Cu-CNTs), and Cu-CNTs with carbon nanofiber tails are obtained. The synthesized carbon nanomaterials have fascinating potential applications in nanometer-sized electronic devices, especially in field-emission applications. -(TAO, X.; ZHANG*, X.; CHENG, J.; LIU, F.; LUO, J.; LUO, Z.; Chem.
