“…The charged precursor is bound and stabilized at the surface via Coulomb forces [83][84][85] in N 2 in a tubular reactor. 64,82 The real Pt content determined by ICP-OES was 2.8% thus the subsequent designation (2.8%) was used for Pt/TiC-CDC.…”

aThe aqueous phase reforming (APR) of xylitol was studied over five Pt/C catalysts. The correlation between physico-chemical properties of the catalysts and catalytic performance was established. The Pt/C catalysts have different textural properties as well as different mean Pt cluster sizes and surface acidity. The average Pt cluster size was investigated by means of CO chemisorption as well as by TEM.The reaction was found to be structure sensitive and TOF linearly increases with increasing average Pt cluster size in the studied domain. The catalysts which possess higher surface acidity favoured higher rates of hydrocarbon production. On the contrary the Pt/C materials with lower acidities generated hydrogen with high selectivity and TOF.

“…[5][6][7][8][9][10] Compared with the carbon supported catalyst which used in proton exchange membrane (PEM) fuel cells, the Pt/TiC catalyst showed a considerable enhancement for the electrooxidation of methanol and CO, accompanied with alleviative CO poisoning effect. [11][12][13] Recently, Chen et al [14] proved that the using of TiC as a support can significantly reduce the consumption of Pt for the HER (Hydrogen Evolution Reaction) . Roderick et al [15] have proved that Pt-Ir on TiC surpassed the other electrocatalysts with a round trip efficiency of 65% in the experiment for the PEM fuel cell/electrolyzer process.…”

“…The presence of D-band at 1360 cm À1 is attributed to the defect of the crystal lattice, irregular edge arrangement and poor symmetry in graphite layer, which can be seen as a breathing mode with A 1g symmetry. 39 The G-band at 1580 cm À1 is expressed as the structural graphite which is due to the stretching vibration of C-C bond in sp 2 conguration with E 2g symmetry in the crystal lattice. All evidence conrms that the le anode carbon monolith is composed of amorphous and graphite carbon.…”

In this work, remelted high carbon ferromanganese was chosen as a consumable anode to produce porous carbon monolith and low carbon ferromanganese at the same time by molten salt electrolysis. During potentiostatic electrolysis, the anode fed manganese ions and iron ions into molten salts, with porous carbon left at the anode and ferromanganese deposited on the cathode. The anode residue was characterized by Xray diffraction, scanning electron microscopy, Raman spectrum and transmission electron microscopy.Results indicated that this type of porous carbon material with a high degree of graphitization has a multimodal pore system consisting of micropores, mesopores and macropores, which is hierarchical carbide derived carbon (CDC). The anode and cathode current efficiencies are estimated to be at least 92% and 80%, respectively. All results implied that it is feasible to prepare carbide derived carbon monoliths with a hierarchical pore structure and low carbon ferromanganese simultaneously by molten salt electrolysis.
