“…Another possible cause of this behavior is the low metal content in the samples. Rynkowski et al [4] reported that they did not detect Ni or Pt species on SiO 2 -TiO 2 with a content of 2.5 wt%. In addition, it is reported that Pt presents a detection limit at 3.0 wt% [15].…”

“…Nevertheless, only few works have been reported for the hydrogenation reaction. As an example, Rynkowski et al [4] reported that for toluene hydrogenation the bimetallic catalyst Ni-Pt/SiO 2 -TiO 2 was more active than the monometallic one with a similar content of Pt.…”

“…It has been shown that the methods employed to prepare catalysts have a considerable influence on the catalyst properties and activities. In fact, several research groups have investigated the factors that influence the various preparation stages [3,[10][11][12]. As an example, Machek et al [12] described the solvent affect on the adsorption of chloroplatinic acid and indirectly the Pt dispersion on activated carbon.…”

A series of Pt 50 Ni 50 supported on MCM-41 catalysts were prepared via wet co-impregnation of the metal salts H 2 PtCl 6 and NiSO 4 Á6H 2 O. The metal salts were reduced using NaBH 4 and catalytic activities of the catalysts were investigated for the hydrogenation of benzene to cyclohexane. The effect of various reduction conditions such as reduction temperature, NaBH 4 concentration and the medium in which reduction was carried out was investigated. Results show that optimum catalytic activity occurs when catalysts are synthesized at 273 K using 0.3 M of NaBH 4 in a medium of ethanol. The variation in reduction rate with reduction conditions influenced the metal particle morphology which effected catalytic activity. Further comparison of the reactivity of Pt 50 Ni 50 with that of the respective monometallic catalysts synthesized at optimum conditions, show that the Pt 50 Ni 50 exhibited superior reactivity. Surface properties of the catalysts were characterized using H 2 -TPR, H 2 -adsorprtion and H 2 -TPD analyzes. Studies on the morphology of the metal particles and composition were obtained via TEM and SEM equipped with elemental analysis.

Nano Ni-W catalysts with different tungsten contents prepared by mixing alkaline nickel carbonate with ammonium tungstate show high activity and good sulfur tolerance for hydrogenation of thiophene-containing ethylbenzene. The catalysts were characterized by XRD, TPR, SEM, Raman and BET. The results show that the activity of the catalysts for ethylbenzene hydrogenation is affected profoundly by W loading and the best result was obtained on catalyst with W/Ni ratio equal to 0.16. The increase of activity of the catalyst can be attributed to the interaction between Ni and W doped and the increase of the surface area of the catalyst.
