1. INTRODUCTION Heterogeneous catalysis, whereby a gas-or liquid-phase reaction is
performed over a solid catalyst, is at the heart of the modern energy and chemical industries. …

The effects of metal particle size in catalysis are of prime scientific and industrial importance
and call for a better understanding. In this paper the origin of the cobalt particle size effects …

Metal hydrides are likely candidates for the solid state storage of hydrogen. NaAlH 4 is the
only complex metal hydride identified so far that combines favorable thermodynamics with a …

The proximity of nanoparticles may affect the performance, in particular the stability, of
supported metal catalysts. Short interparticle distances often arise during catalyst preparation by …

In order to obtain copper catalysts with high dispersions at high copper loadings, the gas
flow rate and gas composition was varied during calcination of silica gel impregnated with …

XPS and acid−base titrations were used to investigate the nature and stability of oxygen-containing
surface groups on carbon nanofibers (CNF) and platinum-containing CNF. During …

A main reason for catalyst deactivation in supported catalysts for methanol synthesis is
copper particle growth. We have functionalized the support surface in order to suppress the …

Metal nanoparticle growth represents a major deactivation mechanism of supported catalysts
and other functional nanomaterials, particularly those based on low melting-point metals. …

To develop structure–performance relationships for important catalysts, a detailed characterization
of their morphology is essential. Using electron tomography, we determined in three …

Here we report on the preparation of Co/TiO 2 catalysts (8 and 16 wt % Co) using deposition
precipitation by ammonia evaporation (DPA) and incipient wetness impregnation with …
