Geometric and electronic approaches to size effects in heterogeneous catalysis

The influence of electronic and geometric factors is considered in the context of the manifestation of size effects in heterogeneous catalytic oxidation and hydrogenation reactions. Both of the

Model studies in heterogeneous catalysis at the microscopic level: from the structure and composition of surfaces to reaction kinetics

Abstract.Heterogeneous catalysis is one of the fields of modern technology, in which a characterization of structural and chemical properties of solid surfaces at the microscopic level is of enormous

An Overview of Palladium Nanocatalysts: Surface and Molecular Reactivity

The use of metallic nanoparticles in catalysis under homogeneous conditions leads to a discussion of their catalytic nature: whether the catalyst behaves as a molecular species or, on the contrary,

Catalytic Consequences of Particle Size and Chloride Promotion in the Ring-Opening of Cyclopentane on Pt/Al2O3

Ring-opening of cyclopentane on alumina-supported Pt particles was studied as a function of Pt particle size in the presence of different Cl contents. With catalysts prepared from a Cl-free

Overlayer Bimetallic Catalysts or Particle Size Effects? A Comparison of Re@Pd Catalysts with Different Particle Sizes

Alumina supported Re@Pd bimetallic overlayer catalysts of different loading, dispersion, and particle size were synthesized using the directed deposition technique. Past computational and empirical

New perspectives on the nature and imaging of active site in small metallic particles: II. Electronic effects

Abstract The science of heterogeneous catalysis is primarily based on surface phenomena, which occur on nanoscale surfaces on active sites with sub-Å dimensions. On these surfaces, only some atomic

Clean preparation of nanoparticulate metals in porous supports: a supercritical route

Here we present the synthesis of nanometre sized silver particles which have been trapped within porous substrates; poly(styrene-divinylbenzene) beads and silica aerogels. This is the first time that

The evolution of model catalytic systems; studies of structure, bonding and dynamics from single crystal metal surfaces to nanoparticles, and from low pressure ( 10−3 Torr) to liquid interfaces

The material and pressure gap has been a long standing challenge in the field of heterogeneous catalysis and have transformed surface science and biointerfacial research. In heterogeneous catalysis,




Abstract Supported metal catalysts are widely used because it is possible to prepare them in a highly dispersed form, consisting of very small microcrystals, which provide a maximum available surface
