A study of Ruthenium catalysts on oxide supports

Surface Science Letters, 1989
Abstract Ruthenium clusters on γ-Al 2 O 3 and SiO 2 supports, prepared by different impregnation methods, are studies by thermal programmed reduction (TPR), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and chemisorption techniques.

Catalyst Supports and Small Particle Catalysts

1998
Many of the useful properties of catalysts arise from reactions between the solid surfaces of the catalysts and various gaseous reactants. Catalysts of large specific surface areas are often desired and they can be obtained by the use of porous bodies.

Application of ZrO2 as a catalyst and a catalyst support

Catalysis Today, 1994
Abstract Examples of the application of ZrO 2 for catalysts and catalyst supports are reviewed. The specificity of the structure and the surface properties including the behavior of surface OH groups are introduced. The catalytic properties of dispersed and promoted ZrO 2 are presented.

Supported Metallocene Catalysts

CATTECH, 2000
Single-site olefin polymerization catalysts have been researched extensively and are now achieving wide acceptance in the polyolefin industry. To achieve commercial significance in the majority of today's commercial processes, these soluble catalysts must be immobilized on a carrier.

Characterisation of Supported Catalysts

1985
The complete characterisation of supported catalysts is extremely difficult due to the inhomogeneous nature of the catalysts themselves. Accordingly a wide range of analytical and spectroscopic techniques have been applied to the problem. No one technique can do more than illuminate one facet of the structure. A typical characterisation procedure would

Catalysts Supported on Fullerenes

2019
Fullerenes (mainly C60) have been evaluated as supports for catalysts under hydrogenation conditions to a lesser extent than other carbon nanomaterials and amorphous carbons. Limited activity of fullerene alone was noted. Both noble metals and transition metals have been tested as active metals.
