N2 - The RF plasma discharge in liquid n-hexane is used to synthesize carbon nanoparticles. The results show that amorphous carbon nanoparticles with size of 5-25 nm are the main product in the plasma in liquid n-hexane. Carbon nano-tubes of average diameter of 19 nm and length of 500 nm are also observed. The energy efficiency for carbon nanoparticles production is 2.9 mg/kJ which is more than 10 times larger than that of typical arc discharge synthesis method. The high speed observation indicates that the RF plasma in liquid has an alternating behaviour and it does not continuously emit light. The OES results show that H and C2 are the main observed species in the plasma. Based on the OES data, it is shown that plasma temperature is 4,030 K and the electron density is 2.54 × 1022 m-3. Our results suggest that this method can be considered as a new route for carbon nanostructures production.
