Heterogeneous Catalysts for Synthetic Applications

Heterogeneous catalyst exists in a different phase than the reactants in a chemical reaction. Typically, the catalyst is solid while the reactants are in the gas or liquid phase. The catalyst is synthesized by impregnation, co-precipitation, sol-gel process or chemical vapor deposition. Heterogeneous catalysis is a process in which the heterogenous catalyst facilitates reactions by providing a surface for the reactants to adhere to, allowing the reaction to occur more efficiently. These catalysts are used in biodiesel production, hydrogenation, oxidation, or coupling reactions allowing for faster, large-scale productions and selective product formation. The Evonik solid heterogeneous catalysts portfolio has been created with a variety of metals: Pd, Pt, Ru, and Rh with the metal present on the active carbon for most. Controlling the percent metal and the structure of the carbon changes the reactivity broadening the application possibilities.

The tables below summarize the applications of these diverse catalysts categorized by reaction type. For a complete application guide, please see the download link below.
