The Effect of Stabilizers on the Catalytic Activity and Stability of Pd Colloidal Nanoparticles in the Suzuki Reactions in Aqueous Solution
Transition metal nanoparticles used in catalysis in solution are stabilized by capping the surfaces that are supposed to be used for catalysis. Determining how these two properties, that is, theExpand
Catalyst parameters determining activity and selectivity of supported gold nanoparticles for the aerobic oxidation of alcohols: the molecular reaction mechanism.
A mechanistic proposal consisting of the formation of metal-alcoholate, beta-hydride shift from carbon to metal and M--H oxidation has been proposed that explains all experimental results. Expand
Immobilization of gold nanoparticles on fused silica capillary surface for the development of catalytic microreactors
Abstract A new reaction setup using a gold-based catalytic microcapillary reactor was developed. In order to immobilize the gold nanoparticles onto the fused silica inner wall, two different linkersExpand
Mechanism of selective alcohol oxidation to aldehydes on gold catalysts: Influence of surface roughness on reactivity
The complete reaction pathway for the selective alcohol oxidation to aldehyde has been obtained from periodic density functional theory (DFT) calculations on a series of catalyst models having AuExpand
Metal clusters on supports: synthesis, structure, reactivity, and catalytic properties.
Opportunities for deeper understanding of the chemistry of supported metal clusters hinge on improvements in characterization techniques such as X-ray absorption spectroscopy and high-resolution transmission electron microscopy. Expand
Molecular approaches to catalysis: Naked gold nanoparticles as quasi-molecular catalysts for green processes
Abstract Gold nanoparticles smaller than ∼2 nm show interesting catalytic properties arising from their size-determined electronic and geometrical structures. They are able to dissociate molecular OExpand
Pore size effect of the DMFC catalyst supported on porous materials
Abstract Activated carbons were employed for the support material of catalyst in the direct methanol fuel cell (DMFC). Until now, most of the papers related to the catalyst of fuel cells reportedExpand
A general synthetic strategy for oxide-supported metal nanoparticle catalysts.
This work describes a synthetic methodology that takes advantage of recent advances in the synthesis of metal and oxide nanomaterials and helps to bring together these two classes of materials for catalysis applications and develops efficient gold catalysts for green chemistry processes. Expand
Selective blocking of active sites on supported gold catalysts by adsorbed thiols and its effect on the catalytic behavior: A combined experimental and theoretical study
Abstract Selective blocking (poisoning) of catalytic active sites of gold catalysts, CeO 2 and TiO 2 supported Au colloids (2.1 and 6.9 nm), was investigated in the aerobic oxidation of benzylExpand
Size-dependent chemistry: properties of nanocrystals.
This article examines the size dependent electronic structure and properties of nanocrystals of semiconductors and metals to illustrate this aspect and discusses the chemical reactivity of metal nanocry crystals which is strongly dependent on the size. Expand
