“…[1][2][3][4][5][6][7] Nevertheless, ACs are accessible and low-cost materials as they are obtained not only from different natural sources, but also from waste materials (which are so converted into added value products). [2][3][4][5][6][7][8][9][10] Thus, ACs are extensively used as solid supports in heterogeneous catalysis due to their high surface areas, chemical stabilities and high adsorptivities are very important features for this purpose. The suitable control of the catalyst preparation from ACs is a crucial issue to reach large efficiency.…”

2 S-F/Pd(II) hybrids on the hydrogenation of 1-octene in methanol as a catalytic test were evaluated. 100 % conversion to n-octane at T = 323.1 K and P = 15 bar, was obtained with both catalysts and most of Pd(II) was reduced to Pd(0) nanoparticles, which remained on the AC surface. Reusing of the catalysts in three additional cycles reveals that the catalyst bearing the F ligand with larger Pd-complexing ability showed no loss of activity (100 % conversion to n-octane) which is assigned to its larger structural stability. The catalyst with the weaker F ligand underwent progressive loss of activity (from 100 % to 79 % in four cycles), due to the constant aggregation of the Pd (0) nanoparticles. Milder conditions, T = 303.1 K and P =1.5 bar, prevent the aggregation of the Pd(0) nanoparticles in this catalyst allowing the retaining of high catalytic efficiency (100 % conversion) in four reaction cycles.

“…According to the charge storage mechanism, supercapacitors can be classified into electrical double layer (EDL) capacitors by absorbing ions from electrolyte solutions onto the electrode surface and pseudocapacitors based on Faradaic redox reactions between electrode and electrolyte [2]. As the most widely used electrode materials, carbon-based materials with EDL mechanism exhibit good stability and higher power capability but lower specific capacitance [3,5,[11][12][13][14]. Transition metal oxides with both EDL and Faradaic mechanism such as RuO 2 [15] and MnO 2 [3] are characterized by higher specific capacitance but poor cycling performance and electrical conductivity [11].…”

“…[6][7][8][9][10] Therefore, a lot of researches have been conducted to fabricate 1D carbon nanomaterial with well controlled chemical composition and morphology using self-assembly solvothermal synthesis, chemical vapor deposition, and nanocasting. [11][12][13][14][15] However, there are several limitations of these synthesis that are rigid reaction conditions, high cost, and complicated synthetic steps.…”

Recently, carbon nanomaterials are attractive for various applications owing to the benefits derived from their high electrical conductivity, chemical stability and large surface to volume ratio. However, the fabrication process of carbon nanomaterials is complicated and exhibits low productivity. Here we report the facile one-pot synthesis of highly porous 1D carbon nanotubes based on three-layered polymer nanofibers by using a dual-nozzle co-electrospinning technique to apply to an energy storage device.Specific capacitance (C G ) of the porous carbon nanotube-based electrode is 401 F g À1 , which is larger than that of the other carbon nanomaterials. Furthermore, the porous carbon nanotube exhibits excellent rate capability and cycle stability due to micro-/mesopores in the carbon structure enhancing the active surface area between carbon and the ions of the electrolytes. This unique fabrication technique is an effective approach for forming large scale highly porous carbon nanomaterials for diverse electrochemical applications.
