Continuous flow hydrogenation using polysilane-supported palladium/alumina hybrid catalysts
Continuous flow systems for hydrogenation using polysilane-supported palladium/alumina (Pd/(PSi-Al(2)O(3))) hybrid catalysts were developed. Our original Pd/(PSi-Al(2)O(3)) catalysts were used successfully in these systems and the hydrogenation of unsaturated C-C bonds and a nitro group, deprotection of a carbobenzyloxy (Cbz) group, and a dehalogenation reaction proceeded smoothly. The catalyst...
متن کاملHydrogenation of carbon monoxide over vanadium oxide- promoted rhodium catalysts
The effect of vanadium oxide as support and promoter on supported rhodium catalysts on the CO hydrogenation has been investigated at 0.15 and 4.0 MPa. Rh/V,O, reduced at 723 K has a good selectivity toward oxygenated products, especially C,-oxygenates, but has a low activity added as a promoter to catalysts consisting and stability. Vanadium oxide of rhodium supported on silica and alumina show...
متن کاملMicrowave synthesis of classically immiscible rhodium-silver and rhodium-gold alloy nanoparticles: highly active hydrogenation catalysts.
Noble metal alloys are important in large-scale catalytic processes. Alloying facilitates fine-tuning of catalytic properties via synergistic interactions between metals. It also allows for dilution of scarce and expensive metals using comparatively earth-abundant metals. RhAg and RhAu are classically considered to be immiscible metals. We show here that stable RhM (M = Ag, Au) nanoparticles wi...
متن کاملRapid Synthesis of Rhodium–Palladium Alloy Nanocatalysts
Noble metals are widely used as catalysts in a variety of key industrial processes. In particular, rhodium is used to catalyze the reduction of NOx to N2 and O2 in exhaust gas abatement and is also used in the conversion of bulk hydrocarbon feedstocks and syngas into more highly oxygenated hydrocarbons (e.g. , hydroformylation). 2] Palladium also plays a myriad of critical roles, including CO-t...
متن کاملCO Hydrogenation over Alumina-Supported Sulfide Cluster Catalysts
Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on AI,O, and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power rate laws for methanation indicated that the surfaces of the catalytic ensembles were not completely saturated by CO, in contrast to the observations for most conventional CO hydroge...
