This study reports the electrocatalytic activity of alloyed Pt10−x–Fex/CNTs (x=1, 2, 3, 4, 5) and Pt/CNTs nanoparticles. These materials were synthesized using the Brust–Schiffrin method and were tested as potential anodic electrocatalysts in a direct methanol fuel cell (DMFC). SEM, EDS, XRD, TEM and TGA studies were performed to confirm the formation of Pt–Fe alloyed nanoparticles. The nanoalloys...
NiMoW-O mixed oxide was obtained by calcination of the ϕy layered precursor (NH4)Ni2OH(H2O)(MoO4)2 (NiMoW-L). Unsupported catalysts were obtained from porous NiMoW-O activated ex-situ under a H2S/H2 (15% v/v) mixture at temperatures in the range of 673–823K. Activation temperature was crucial in catalytic activity for dibenzothiophene (DBT) hydrodesulfurization (HDS). The best temperature of activation...
Selectivity and kinetic studies of the Pd-catalysed hydrogenation of 2-butyne-1,4-diol were performed in a single capillary channel, and monoliths consisting of 1256 capillaries and 5026 capillaries in (I) the pressure range 100–300kPa (II) the temperature range 298–328K using a 30% v/v 2-propanol/water solvent. All reactors were operated in downflow mode such that the reaction fluid was in Taylor...
