Structural, mechanical, and electrical properties of carbon nanoparticles synthesized from diesel

Abstract

Downloaded by [University of Nebraska, Lincoln] at 03:05 10 October 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 We studied the elemental analysis, structural morphology, mechanical, and electrical properties of carbon nanoparticles synthesised from diesel. The spherical carbon particles size in the range of about 10 to 80 nm in diameter was observed in SEM studies which were identified by AFM study as an aggregation of carbon particles of average size 2.5 nm. The surface rms of carbon nanoparticle thin film (CNTF) was measured directly by AFM and found 0.22 nm. The DMT elastic modulus of carbon nanoparticles (CNP) was measured by PeakForce QNM mode of AFM. The minimum and maximum elastic modulus was measured of 0.40 GPa and 43.89 GPa respectively. The resistivity, conductivity, magneto resistance, mobility and average Hall coefficient were measured by 'Ecopia Hall-effect measurement system' by 4-point Van der Pauw approach at ambient condition. We demonstrated I-V characteristic at the Indium/CNTF thin film interface which is accompanied by rectifying behavior.

AFM and Van der Pauw Measurements of Carbon Nanoparticles Prepared from Kerosene

“…Using Diesel, which is an affordable and cheap material, carbon nanoparticles of size 10 to 80 nm in diameter was synthesized. The electrical property study revealed a rectifying behavior which confirms a potential application for the CNPs synthesized from low-cost method (Hossain et al, 2016). In the current study the electrical property measurements will be compared with that of CNPs synthesized from diesel in order to determine which will be better suited for electrical applications.…”

“…As a result, in the reverse bias, the Schottky barrier height increases with decreasing the work function of the metal electrode, which is responsible for decreasing of current than the forward biascurrent. In Table-1, different parameters of electrical properties for CNPs from kerosene and diesel (Hossain et al, 2016) are compared. It is found that the thin film of CNPs from diesel has lower resistivity than graphitic carbon (at least three orders of magnitude) (Hossain et al, 2016), whereas the thin film of CNPs from kerosene shows resistivity at least three orders of magnitude higher than graphitic carbon.…”

As for conductivity, carbon nanoparticles thin film from diesel (Hossain et al, 2016) shows conductivity higher than graphitic carbon at basal plane by three orders of magnitude, whereas carbon nanoparticles from kerosene shows three orders of magnitude lower than graphitic carbon at basal plane.…”

One-step synthesis and characterization of carbon nanospheres via natural gas condensate pyrolysis

“…Carbon core shell nanospheres were fabricated by Ehab et al [28] using bitumen-derived coal obtained from pyrolysis of petroleum bitumen at 600°C in argon atmosphere with average diameter of about 200-400nm in the product. Mohammad et al [29] synthesized CNSs form the incomplete combustion of diesel with controlled air oxygen in special type of round bottom flax of glass, with size in the range of about 10-80nm in diameter. In addition, Nandiyanto et al [30] synthesized small CNSs from commercially available liquefied petroleum gas using a homemade burner that was connected with a flow of air (600 mL/min).…”

Graphene oxide/carbon nanoparticle thin film based IR detector: Surface properties and device characterization

“…42,43 In this work, GO was prepared via modified synthesis protocol; 44 and, whereas, CNP was synthesized from diesel which has been described elsewhere. 45 Compared to pure graphene, GO exhibits a significant loss of conductivity. These sheets need to be reduced to restore the sp 2 hybrid network and thus reintroduce the conductive property.…”
