Bio-based production of carbon nanotubes via co-pyrolysis of eucalyptus oil and ferrocene

How reduction temperature affects the properties of carbon nanotubes growing over the Fe–MgO/Al2O3catalyst

“…A strong peak near 1580 cm −1 (designated as the G-band) is due to the CC tangential vibration of sp 2 hybridized carbon, representing the formation of graphitized CNTs. 36 Another strong peak near 1350 cm −1 (designated as the D-band) represents the vibration of other hybrid carbon atoms, 37 such as amorphous carbon and lattice defects. 38 The D band and G band of all four spectra were similar, and the Raman intensity ratio ( I D / I G ) of the D band and G band can be used to measure the structural regularity of carbon nanotubes, and I D / I G gives the degree of surface defects and lattice distortion of the graphite layer within the carbon material.…”

Mesoporous carbon encapsulated zinc oxide nanorods derived from plant species ‘Argyreia sharadchandrajii’ for live cell imaging of drug delivery and multimodal bioactivities

“…41 In contrast to other carbon nanomaterials, which necessitate complicated fabrication methods, bioderived carbon, which is porous in nature, and black-coloured carbonaceous solid products can be obtained by slow pyrolysis of plant biomass at the highest temperature around 700-800 1C. 42,43 Bioderived carbon nanomaterials sculptured via pyrolysis have a high specific surface area (SSA), are thermally stable, and are porous in nature. [44][45][46] Biomass-derived carbon as a replacement for chemically synthesized carbon materials will not only contribute towards waste management but also provides the potential for large-scale production.…”

Synthesis of magnetic carbon nanotubes via Co-pyrolysis of eucalyptus oil with bimetallic Ni-Fe catalyst

“…G-band at Raman shift of 1,585 cm -1 can be assigned to the vibration of sp 2 bonded carbon atom. The band is applied to specify CNTs [56]. From this experiment, ID/IG decreased from 1.01 to 0.83 when the molar ratio was increased from 2:1 to 5:1.…”

“…A peak at Raman shift of 1,588 cm -1 responds to the vibration of sp 2 bonded carbon atom which is called G-band. Generally, G-band was applied to identify CNTs [56]. The ratio of intensity of D-band to G-band (ID/IG) was used to identify the crystallinity of carbon product.…”

“…Although total mole of Fe and Ni (mol Fe +mol Ni ) in each catalyst were different as shown in Table C1, in calculation of molar ratio of eucalyptus oil to catalyst, the mole of catalyst was assumed to their average value (2.63 mmol) because quality and quantity of CNTs depended on total amount of eucalyptus oil although feed flowrate was fixed [56]. Therefore, amount of eucalyptus oil feed was fixed in the study effect of catalyst.…”
