Abstract

See full text

Processes for preparing supported gold nanoparticle catalysts are provided. In an exemplary embodiment, the process includes adding a solution of a phosphorus compound to a solution of chloro (dimethyl sulfide) gold (I) to obtain a solution of chloro (phosphorus compound) gold (I) complex, adding the solution of chloro (phosphorus compound) gold (I) complex to a solution of silver nitrate to obtain a solution of nitro (phosphorus compound) gold (I) complex, applying the solution of nitro (phosphorus compound) gold (I) complex to a metal hydroxide support, drying the metal hydroxide support; and calcining the dried metal hydroxide support to form the supported gold nanoparticle catalyst. Supported gold nanoparticle catalysts prepared by the process and processes for oxidizing ethylene to ethylene oxide in the presence of the supported gold nanoparticle catalysts are also provided.
