TiO2 supported Pd@Ag as highly selective catalysts for hydrogenation of acetylene in excess ethylene.
A novel TiO2 supported core-shell (Pd@Ag) bimetallic catalyst was fabricated via the sequential photodeposition method. The Ag shell effectively blocks the high coordination sites on the Pd core, and therefore pronouncedly enhances the ethylene selectivity for the catalytic hydrogenation of acetylene in excess ethylene.
متن کاملHigh-performance supported catalysts with an ionic liquid layer for the selective hydrogenation of acetylene.
Pd-Ag shell catalysts impregnated with two different ionic liquids show considerable improvements both in ethylene selectivity and reduced ethane formation in the selective hydrogenation of acetylene under tail-end conditions.
متن کاملSelective Hydrogenation With Copper Catalysts: II. Kinetics
To explain the unusually high selectivity of copper catalysts toward linolenate, model compounds were hydrogenated (150 C and atmospheric pressure) and the reaction products analyzed. Products varied depending upon location of the double bonds. Monoenes were not reduced by copper chromite except when the double bond was next to a carboxyl group. Dienes with isolated double bonds also were not r...
متن کاملSilica-supported isolated gallium sites as highly active, selective and stable propane dehydrogenation catalysts.
Single-site gallium centers on the surface of silica are prepared via grafting of [Ga(OSi(OtBu)3)3(THF)] on SiO2-700 followed by a thermolysis step. The resulting surface species corresponds to well-defined tetra-coordinate gallium single-sites, [( 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 00000000...
