TiO2 supported Pd@Ag as highly selective catalysts for hydrogenation of acetylene in excess ethylene.

High-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.

A DFT + U study of acetylene selective hydrogenation over anatase supported PdaAgb (a + b = 4) cluster.

It is well known that the addition of Ag into Pd can promote the selectivity of acetylene hydrogenation to ethylene, and early theoretical studies focus on ideal single crystal model catalysts, so it is worth studying relatively realistic catalyst models, such as metal oxide supported PdAg systems. In this work, the reaction mechanisms for acetylene selective hydrogenation on the anatase TiO2(1...

Acetylene and Ethylene Hydrogenation on Alumina Supported Pd-Ag Model Catalysts

Adsorption and co-adsorption of ethylene, acetylene and hydrogen on Pd-Ag particles, supported on thin alumina films, have been studied by temperature programmed desorption (TPD). The TPD results show that adding of Ag to Pd suppresses overall hydrogenat ion activity but increases selectivity towards ethylene, i.e. similar to that observed on real catalysts. The results are rationalized on the ...

An Egg-Shell Pd-Ag/ α -Al 2 O 3 Catalyst for Tail-End Acetylene Selective Hydrogenation

Intermetallic Compound AlPd As a Selective Hydrogenation Catalyst: A DFT Study

Recently, it has been demonstrated that intermetallic compounds composed of Pd and Ga or Co and Al provide excellent selectivity for the hydrogenation of acetylene to ethylene. Motivated by experimental works on GaPd catalysts, we have performed a detailed ab initio study of acetylene hydrogenation by the pseudo 5-fold (120) surface of the isostructural and isoelectronic AlPd compound crystalli...
