In chemistry, a catalyst support is the material, usually a solid with a high surface area, to which a catalyst is affixed. The activity of heterogeneous catalysts and nanomaterial-based catalysts occurs at the surface atoms. Consequently, great effort is made to maximize the …

Highly active iridium–rhenium catalyst condensed on silica support for hydrogenolysis of glycerol to 1,3-propanediol. ... Fig. S3). In spite of the large loss of Re in the current preparation method, the low actual amount of Re in the highly active catalyst gives us hope that more inexpensive catalyst will be developed in the future.

Catalyst support plays an important role for supported metal catalysts in bringing out the capability of the supported metal as a catalytically active center. Generally, materials for catalyst supports show high surface area, chemical stability as well as capability for dispersing metal particles highly over the surface.

A heterogeneous catalyst has active sites, which are the atoms or crystal faces where the reaction actually occurs. Depending on the mechanism, the active site may be either a planar exposed metal surface, a crystal edge with imperfect metal valence or a complicated combination of the two.

• The Catalyst 4507R switch and the 4510R switches are the only Catalyst 4500 series switch that support supervisor engine redundancy. • The Catalyst 4510R switch supports the WS-X4516 supervisor engine only. The Catalyst 4507R switch supports the other redundant supervisor engines (Supervisor Engine II-Plus and Supervisor Engine IV and WS ...

The metal–oxide interaction changes the surface electronic states of catalysts deployed for chemical conversion, yet details of its influence on the catalytic performance under reaction conditions remain obscure. In this work, we report the high activity/stability of a ceria-supported Ru–nanocluster (<1 nm) catalyst during the dry reforming of methane. To elucidate the structure ...Cited by: 3

KF 542 is an active support material supplied in both lobed and ring shapes for bed grading applications to control fouling and pressure drop build-up. It has low activity to favor slow removal of the most reactive feed components. KF 647. KF 647 is a catalyst especially designed for high capacity and activity for contaminant removal.
