“…These include the hydrogenation of light alkenes [23][24][25][26][27], aldehydes [21,[28][29][30][31][32][33], polycyclic aromatic hydrocarbons [34], nitrobenzene [35], and cyclohexene [36]. They have also been used in alkene hydroformylation [37], vacuum residue hydroprocessing [38,39], ammonia and Fisher-Tropsch synthesis [40][41][42], cyclohexanol dehydrogenation [43], NO decomposition [44] and aniline oxidation [45,46]. However, CNFs have not been applied to bio-oil upgrading in supercritical water and more research is needed to develop suitable catalysts for this upgrading technology.…”

This work addresses the preparation, characterisation and screening of different Ni-Co catalysts supported on carbon nanofibres (CNFs) for use in the upgrading of bio-oil in supercritical water. The aim is to improve the physicochemical properties of bio-oil so that it can be used as a fuel. The CNFs were firstly oxidised in HNO 3 and afterwards subjected to a thermal treatment to selectively modify their surface chemistry prior to the incorporation of the metal active phase (Ni-Co). The CNFs and the supported catalysts were thoroughly characterised by several techniques, which allowed a relationship to be established between the catalyst properties and the upgrading results.The use of Ni-Co/CNFs for bio-oil upgrading in supercritical water (SCW) significantly improved the properties of the original feedstock. In addition, the thermal treatment to which the fibres were subjected exerted a significant influence on their catalyticproperties. An increase in the severity of the thermal treatment led to a substantial reduction in the oxygen content of the CNFs, mainly due to the removal of the less 2 stable oxygen surface groups, which allowed their surface polarity to decrease. This decrease resulted in less formation of solid products. However, it also reduced the H/C and increased the O/C ratios of the upgraded liquid. Therefore, a compromise between the yield and the properties of the upgraded bio-oil was achieved with a Ni-Co supported on a CNF with a moderate amount of oxygen surface groups.

“…Carbon nanotubes (CNTs) with unique structure and properties such as well-defined hollow interiors, inert surface properties, and resistance to acid and base environment have been proven to be excellent candidates as support in catalytic reactions [1][2][3][4][5][6][7] and energy storage and conversion medium [8][9][10][11]. Structural parameters of CNTs such as inner diameter, wall thickness, length, crystallinity, and electronic structure have a great influence on the performance of the supported particles or loaded matters [12][13][14][15].…”

One of the most unique structural characteristics of carbon nanotubes (CNTs) differentiating from other carbon materials is their hollow nanochannles, which can be utilized for encapsulating and loading foreign matters. The anodic aluminum oxide (AAO) template technique enables the diameter, length, and cap structure control of the replicated CNTs, and thus shows advantages in pore structure control over the traditional CNT growth approaches. This review details the synthesis of CNTs with tunable diameter, length, wall thickness, and crystalline by using the AAO template method. The doping of heteroatoms and filling of foreign matters into AAO-CNTs are also addressed. Moreover, the main challenges and developing trends of the AAO template method are discussed.carbon nanotubes (CNTs), anodic aluminum oxide (AAO) template method, controllability Citation:Hou P X, Liu C, Shi C, et al.

“…Our previous study found similar effects of Mn addition in Ru _ Mn/Al2O3 systems. The BET surface areas and pore volumes of CNTbased catalysts were lower than for γ-Al2O3-based catalyst ( Table 1), but these values were analogous to reported values for CNT-based catalysts 6) . The pore volume of CNT-based catalysts was in the order RuMn/ CNT＞Ru/CNT＞CNT, in accordance with the peak area of differential pore volume (d(Vp)/d(rp)) between ca.…”

Fischer-Tropsch syntheses were carried out in a slurry phase over Mn-modified Ru/carbon nanotube (CNT) catalysts using hexadecane as a solvent. CO conversion and C5＋ selectivity were dependent on the Ru and Mn concentrations as well as the reaction temperature. The activity of the catalyst containing optimized amounts of Ru and Mn was very similar to that of Ru _ Mn/γ-Al2O3, although the initial activity of CNT-based catalysts after 3 h was about 10％ lower than that of Al2O3-based catalyst. Presumably removal of chloride from RuCl3 to form active metallic ruthenium species on the CNT catalyst was enhanced by the addition of manganese.
