The large amount of carbon dioxide produced by burning fossil fuels is considered as the "culprit" of global warming. However, German researchers have found that with the help of a metal catalyst, carbon dioxide and hydrogen can be used to produce methanol for industrial use under milder conditions.
Methanol is an important chemical raw material and a clean liquid fuel, and is widely used in medicine, pesticides, fuels and other fields. At present, industrial production of methanol is mainly accomplished by hydrogen and carbon monoxide under high temperature and pressure and heterogeneous catalysis.
Researchers at Aachen University in Germany reported in a new issue of the German journal Applied Chemistry that they found that in a homogeneous catalytic action of a metal catalyst rhodium-phosphine complex, carbon dioxide and hydrogen can Methanol is produced in a pressurized solution and one carbon dioxide molecule and three hydrogen molecules react to produce methanol and water. Researchers say that using this method to convert carbon dioxide and hydrogen into methanol is a new way of thinking and they will continue to look for more suitable catalysts.
Participation in the researcher also believes that the use of carbon dioxide, the greenhouse gas that people want to reduce emissions, is an ideal process, but it has very high demands on the catalyst and they will continue to look for more suitable catalysts. (Reporter Guo Yang)
