A Highly Active Cu/ZnO/Al2O3 Nanofiber Catalyst for Methanol Synthesis through CO2 and CO Hydrogenation

Methanol is one of the most important feedstocks for the organic chemical industry, its application as a vehicle fuel is also rapidly increasing. Methanol synthesis from a mixture of H2, CO and a small amount of CO2 over Cu/ZnO/Al2O3 catalyst has long been commercialized. In addition, the synthesis of methanol through CO2 hydrogenation has drawn attention since it further has the merit of eliminating the greenhouse gas, CO2. The key to improving the methanol synthesis process is still the development of the catalysts with high activity. And many methods have been reported for improving the activity of methanol synthesis catalysts recently.
