Platinum group metal catalysts are widely used in chemical processes for reactions ranging from gas phase oxidation through selective hydrogenation of chemical, petrochemical, and pharmaceutical feedstocks to fuel cell power generation. All six of the platinum group elements have significant catalytic properties; however, platinum, palladium, rhodium, and ruthenium are the most widely used.

Although platinum group metals are more expensive in initial cost than base metal catalysts, they often prove to be more reactive and selective, and require less severe reaction conditions. In addition, the spent catalyst can be recovered and the precious metal reprocessed into fresh catalyst.

Johnson Matthey has served the platinum group metals industry for over 200 years. With our considerable experience and expertise in the manufacture of catalysts and in catalyst technology, we welcome the opportunity to help develop new catalysts to meet your unique requirements and improve your processing.

Homogenous Catalysts
Homogenous catalysis is a growing area in the chemical industry. Where highly specific reactions are desired, homogenous catalysis provides an excellent choice. Also, if a reaction occurs in the presence of a homogenous catalyst, then by definition it occurs in one phase, normally in the liquid phase. The metal in a homogenous catalyst is more effectively utilized then is the case in heterogenous systems. This means that processes can be operated under mild conditions with significant savings in energy related operating costs. Homogenous catalysts operate with relatively long lifetime and the use of advanced technologies has reduced catalyst poisoning and improved catalyst longevity.
