According to the Xinhua news, carbon dioxide that produced by the burning of fossil fuels is considered as the “culprit” of global warming. However, German researchers found that with the help of a metal catalyst, carbon dioxide and hydrogen can be generate methanol with industrial use under a mild condition. At present, the industrial production of methanol from hydrogen and carbon monoxide under high temperature and pressure and heterogeneous catalysis.
The researchers of Germany RWTH Aachen University reported on a German journal Applied Chemistry, in their experiments, they found that due to a homogeneous catalytic effect of a metal catalyst ruthenium (CAS No. is 7440-18-8) - phosphine complexes, carbon dioxide and hydrogen generated methanol in the pressurized solution. A carbon dioxide molecule and three hydrogen molecules can generate methanol (CH4O, CAS number is 67-56-1 )and water after their reaction. The researchers said that using this method that converting carbon dioxide and hydrogen into methanol is an exploration of new ideas, they will continue to find a more suitable catalyst.
People who participated in this research also believe that, using carbon dioxide which is a greenhouse gase that people want to reduce emission to produce methanol is is an ideal processing idea. However, this process has a very high demand on catalyst, the researchers will continue to find a more suitable catalyst.
