“…14 Less expensive CNT has become a novel and attractive catalyst support due to their unique properties such as high surface area, proper pore sizes, great stability and remarkable electronic conductivity. [15][16][17] Few reports showed that CNT could be used as catalyst support, for example, the hydrotreating of palmitic acid over Mo/CNT 18 ; the hydrotreating of heavy oil over CoMo/CNT 19 ; the conversion of bio oils over Co/CNT. 20 However, there is no report about CNT supported Ni-HPW catalysts.…”

The nickel (Ni) and phosphotungstic acid (HPW) supported on carbon nanotubes (CNT) were prepared by impregnation method for hydroprocessing of Jatropha oil. The Ni-HPW/CNT catalyst was characterized by XRD, XPS, FT-IR, N2 adsorption-desorption, SEM, NH3-TPD, and TGA. The effects of reaction parameters, such as reaction temperature (280–400[Formula: see text]C), time-on-stream (0–100[Formula: see text]h), types of support, the amount of added HPW, and coking deposition were investigated. The cracking performance was evaluated by gas chromatography (GC). The yield of C15–C18 alkanes was 88.5[Formula: see text]wt.%, Iso/n ratio was 0.8 and conversion was 97.7% at 320[Formula: see text]C, 3.0[Formula: see text]MPa and 1.0/h over the Ni-HPW/CNT catalyst, while the yield of [Formula: see text] alkanes reached 51.9[Formula: see text]wt.% at 400[Formula: see text]C. The distribution of products could be adjusted by reaction temperature. The cracking performance was elevated by the addition of HPW and the electrical conductivity. The C15–C18 alkanes were further cracked through two cracking circulations. Meanwhile, the catalyst was used without sulfurization and the cracking process was green.

“…Although, several reviews concerning the separation/growth control of SWCNTs have been published recently, a comprehensive review on the use of highly purified nanotubes for a diverse range of potential applications is yet to be reported. Hence, the main focus in this review is to summarize and critically discuss the state‐of‐the‐art of the current research progress on applying this range of promising materials in a comprehensive range of fields.…”

Single-walled carbon nanotubes (SWCNTs) exhibit outstanding properties that make them appealing in a wide range of applications. However, their properties are variable depending on the tube helicity (chirality), which has been a challenge for a long time and needs to be effectively controlled. In recent years, tremendous efforts have been made to control the electrical type/chirality of nanotubes through both direct controlled synthesis and postsynthesis separation methods. Driven by these breakthroughs, the applications of separated families of SWCNTs in various fields have emerged as a new topic of research. In this Review, an overview of recent advances in the use of highly purified and well-separated SWCNTs in a comprehensive range of applications is presented including photovoltaics, transistors, batteries, sensors, light emitters, biological/medical fields, and others. Finally, important future directions for the utilization of separated SWCNTs in these fields are provided.

“…В данной работе in silico исследуется размерный эффект НСПУНТ на основе одностенных УНТ (16, 0), заключающийся во влиянии размера соты (окна, образованного контактами трубок) на электронную структуру, проводимость, спектр и величину фототока. Трубки (16, 0) были выбраны в связи с тем, что: именно эти трубки относятся к наиболее часто синтезируемым [16]; благодаря малому периоду трансляции атомной сетки этих трубок (в отличие от хиральных) можно проводить исследования наносетчатых плeнок, применяя высокоточные квантовые методы. Также отметим, что именно одностенные УНТ (ОУНТ) с полупроводниковым типом проводимости составляют подавляющее большинство среди синтезируемых трубок.…”

The atomic structure, electronic and optoelectronic properties of nanosized films of carbon nanotubes with seamless cross-shaped X- junctions are studied. It is established that the topology of the arrangement of non-hexagonal elements in the contact region of nanotubes determines the energy stability of the atomic structure. It is revealed that the pore size of the film determines the type of conductivity. At the smallest pore sizes, the film is characterized by a metallic type of conductivity; with an increase in pore size, the gap in the band structure also increases and the film becomes semiconductor. Films with a minimum gap size exhibit good photovoltaic properties. The photocurrent for the considered film models can reach 2.4 mA•cm-2 in the atmosphere and 3.25 mA•cm-2 outside the atmosphere. The presence of a gap in the band structure makes nanosized films promising for nanoelectronics and optoelectronics.
