“…Nanomaterials 2022, 12, x FOR PEER REVIEW 11 of 54 catalytic metal (Ct, such as Ni, Co, Fe, Pd) and transition metal (Me, such as Ti, V, Cr, Zr, Nb, Mo, Ta, W, Re) in an inert or a mixture of argon and nitrogen atmosphere for the achievement of conducting DBLs for the growth of VACNT. As previously published [113], the same team achieved a successful growth of well-developed VACNT only on Co-Zr-N-(O) alloy with specified properties of the DBL and CVD process of CNT growth (given in Table 3). Thus, they achieved growth of multi-layered VACNT with the rate of ~250 nm s −1 and a maximal CNT length of around 35 µm (Figure 7).…”

Vertically aligned carbon nanotubes (VACNT) are manufactured nanomaterials with excellent properties and great potential for numerous applications. Recently, research has intensified toward achieving VACNT synthesis on different planar and non-planar substrates of various natures, mainly dependent on the user-defined application. Indeed, VACNT growth has to be adjusted and optimized according to the substrate nature and shape to reach the requirements for the application envisaged. To date, different substrates have been decorated with VACNT, involving the use of diffusion barrier layers (DBLs) that are often insulating, such as SiO2 or Al2O3. These commonly used DBLs limit the conducting and other vital physico-chemical properties of the final nanomaterial composite. One interesting route to improve the contact resistance of VACNT on a substrate surface and the deficient composite properties is the development of semi-/conducting interlayers. The present review summarizes different methods and techniques for the deposition of suitable conducting interfaces and controlled growth of VACNT on diverse flat and 3-D fibrous substrates. Apart from exhibiting a catalytic efficiency, the DBL can generate a conducting and adhesive interface involving performance enhancements in VACNT composites. The abilities of different conducting interlayers are compared for VACNT growth and subsequent composite properties. A conducting interface is also emphasized for the synthesis of VACNT on carbonaceous substrates in order to produce cost-effective and high-performance nano-engineered carbon composites.

“…Рассмотренная система не является единственной. В нашей предыдущей работе [6] показано, что в системе Co−Zr−N−O образовалось интерметаллическое соединение и рост массива также останавливался спустя некоторое время от начала процесса. Однако при этом высота массива была иной и составляла 12 µm.…”

Поступило в Редакцию 12 мая 2016 г.Экспериментально и теоретически показано, что замедление скорости роста углеродных нанотрубок на тонкопленочных катализаторах может быть обу-словлено формированием интерметаллических соединений, которые затрудняют поступление углерода из объема. В частности, при росте углеродных нанотру-бок из системы тонких пленок Ti и Ni на поверхности капли катализатора формируется слой карбида титана. Рассчитана кинетика роста нанотрубки в этом случае и определены кинетические коэффициенты, которые определяют скорость роста.

“…Among the various techniques being used to synthesize CNMs, the chemical vapor deposition (CVD) is considered as the most promising technique, due to its versatility and suitability for large scale production. In CVD process and under tunable growth conditions, a statistical study should be conducted to achieve an adequate evaluation of the optimal growth conditions for CNMs, such as the utilized catalyst, carbon precursor type and flow rate, growth temperature and reaction time (Alayan et al 2019;Gromov et al 2016).…”

The present work investigates the effect of the type of carbon precursor on the adsorptive proficiency of as-prepared carbon nanomaterials (CNMs) for the removal of methylene blue dye (MB) from aqueous media. A comparison study was applied to assess the growth of CNMs from the decomposition of methane (CNMY1) and acetylene (CNMY2) using response surface methodology with central composite design (RSM/CCD). The produced nanomaterials were characterized using FESEM, EDX, TEM, BET surface area, Raman, TGA, FTIR, and zeta potential. The as-prepared adsorbent displayed different morphologies and under the experimental conditions, 10 mg of CNMY1 and CNMY2 was responsible for 97.7 % and 96.80% removal of dye. The maximum adsorptive uptake predicted by Langmuir isotherm was about 250 and 174 mg/g for CNMY1 and CNMY2, respectively. The as-synthesized carbon nanomaterial in this study could be explored as a great potential candidate for dye-bearing wastewater treatment.
