Direct Synthesis and Characterization of Carbon Nanotube Films Prepared by Premixed Ethanol Flame

Abstract: Carbon nanotube (CNT) films were one-step catalytically synthesized on silicon substrates by the premixed ethanol flame (PEF). Ferric nitrate and copper nitrate with diverse concentrations, as catalyst precursors, were respectively dissolved into the absolute ethanol to form PEF which could simultaneously offer heat source, carbon source and catalysts. More CNT films were synthesized on silicon substrates when first placed between the core and inner flame and then moved into location between the inner and oute… Show more

“…ID/IG can be used as a parameter to approximate the order degree of the number of defects present on the CNT surface [35]. A high value of this ratio means defects on the carbon surface and low degree of graphitization [36]. It was found that the ID/IG ratio increases considerably after the acid treatment, as can be seen in Table 2.…”

“…This ratio is directly related with the structure of the carbon material [33] and it can be used as a parameter to approximate the number of defects present on the MWCNT surface [34]. A high value of this ratio means defects on the carbon surface and low degree of graphitization [35]. Table 2 shows the I D /I G ratio and it can be seen that the ratio increases considerably after the acid treatment.…”

“…Esta relación puede usarse como parámetro para estimar el grado de ordenamiento y la cantidad de defectos presentes en la superficie de los NTC (Katagiri et al, 1988). Por ejemplo, un valor alto de esta relación significa que existen defectos en la superficie y un bajo grado de grafitización (Lu et al, 2012).…”
