Surface-Mediated Self-Coupling of Ethanol on Gold

摘要

Gold-based catalysis has received tremendous interest since the discovery that gold nanoparticles supported on reducible metal oxide supports promote the catalytic oxidation of CO and alkenes at low temperature. More recently, the use of gold catalysts to facilitate the aerobic oxidation of alcohols has become the center of attention, affording the possibility of producing carbonyl derivatives through energy-efficient processes. In particular, ethanol is a potential future feedstock and its purification and conversion is of great importance for the chemical industry. Its derivative carbonyl compounds are important industrial chemicals and intermediate reagents that have wide applications in the food and perfume industries and other areas of synthetic chemistry.
