Catalysts: Homogeneous Catalysts, Heterogeneous Catalysts, and Fuel Cell Catalysts - Alfa Aesar

Catalysts

Precious Metal Compounds and Homogeneous Catalysts

Alfa Aesar offers a full range of precious metal salts and solutions manufactured to stringent specifications. Homogeneous catalysis provides an excellent choice where highly specific reactions are desired including chiral transformations. Our homogeneous catalysts can be used in a wide range of chemical transformations. Please note our FibreCat® Homogeneous Catalysts, which combine the selectivity of homogeneous catalysts with the ease of handling and separation of heterogeneous catalysts.

Catalysts in varying purities and concentrations

Due to their high selectivity, precious metal chemicals are often the first choice as heterogeneous catalysts for a wide variety of reactions, including hydrogenation, hydrosilation, isomerization and carbonylation. Alfa Aesar carries a wide selection of purities and concentrations for a broad range of applications, including organic synthesis in the pharmaceutical industry. We offer a unique collection of chiral ligands for asymmetric hydrogenation, novel palladium coupling catalysts, platinum group metal (PGM)-based heterogeneous catalysts as well as Sponge Nickel catalysts.

Fuel cell catalysts for anodes, cathodes, electrodes

Johnson Matthey is a leading developer of catalysts and other products for fuel cell research and development. Alfa Aesar exclusively offers these products from stock in bulk and semi-bulk quantities. The HiSPEC® line of precious metal catalysts provides superior performance in proton exchange membrane (PEM) and direct methanol fuel cells, for fuel cell research. HiFUEL® fuel processing catalysts and gas treatment products are base metal catalysts for use in fuel cell and other distributed hydrogen processing applications. Alfa Aesar offers a variety of fuel cell components, including Nafion® membranes, Toray carbon paper, cathodes, anodes and membrane electrode assembly (MEA) products.

Metal Scavenger Products

The use of metal catalysts within the pharmaceutical industry allows the efficient transformation or combination of molecules that would otherwise be unfeasible. However, these metals can become an impurity in the final product. Smopex®, QuadraPure, QuadraSil metal scavengers offer one of the most efficient options for removing these metal impurities.
