Amine grafted silica supported CrAuPd alloy nanoparticles: superb heterogeneous catalysts for the room temperature dehydrogenation of formic acid.
Herein we show that a previously unappreciated combination of CrAuPd alloy nanoparticles and amine-grafted silica support facilitates the liberation of CO-free H2 from dehydrogenation of formic acid with record activity in the absence of any additives at room temperature. Furthermore, their excellent catalytic stability makes them isolable and reusable heterogeneous catalysts in the formic acid...
متن کاملUltimate size control of encapsulated gold nanoparticles.
We report an original and scalable synthesis pathway to produce encapsulated gold nanoparticles. Precise control of the gold particles is achieved in the range of 1-10 nm through the impregnation of silicalite-1 with a controlled concentration of gold solution, followed by dissolution-recrystallization of the zeolite.
متن کاملRole of Water in Formic Acid Decomposition
Formic acid decomposes primarily to CO and H2 0 in the gas phase, but to CO, and H, in the aqueous phase. Ab-initio quantum chemical calculations were performed, using Hartree-Fock and density functional methods, to seek an explanation for this behavior. The effect of water on the two decomposition pathways and on the isomerization of formic acid was determined. The transition state structures ...
متن کاملEfficient electrocatalytic oxidation of formic acid using Au@Pt dendrimer-encapsulated nanoparticles.
We report electrocatalytic oxidation of formic acid using monometallic and bimetallic dendrimer-encapsulated nanoparticles (DENs). The results indicate that the Au147@Pt DENs exhibit better electrocatalytic activity and low CO formation. Theoretical calculations attribute the observed activity to the deformation of nanoparticle structure, slow dehydration of formic acid, and weak binding of CO ...
متن کاملGold nanoparticles encapsulated in porous carbonw
Gold was considered catalytically inactive until 1987, when Haruta and co-workers found that gold nanoclusters supported by metal oxides showed high activity toward CO oxidation even below room temperature. Since then, there has been intense interest in the use of Au nanoparticles (NPs) to catalyse a variety of reactions, including low temperature oxidation of CO, selective oxidation of alcohol...
