The process of changing CO2

The process of changing CO2 in the air into organic raw materials oxalic useful.
In the presence of CO2 in the air, the catalyst (left) reacts to form a complex that contains two oxalate (mostly red), which can be liberated with acid treatment. Cu green, N blue, S yellow, O red, and C black.

In a study with implications for global warming show, the researchers have created a new way to eliminate the greenhouse gas CO2 from the air and form a probable organic materials useful in the process (Science 2010, 327, 313). This technique is still at the demonstration stage but promises to other CO2 foreclosure strategy.

Tool-making process prior to "fix" CO2 include the stoichiometric reaction of the hydroxide and carbonate or bicarbonate catalyst to form the transformation of organic compounds like formaldehyde and methanol. Catalytic conversion more efficient and practical for use in large scale, but the catalyst end - the end can not be used in CO2 in the air because they also reduce oxygen, which is in the air at a very high tingkata of the CO2. In addition, they are not tselektif, creating a mixture of organic products.

Expert Elisabeth Bouwman inorganic chemistry from the University of Leiden, the Netherlands, and his colleagues have now been mengmbangkan a catalyst that reacts with CO2 from ambient air to form a single product oxalate, a useful raw material for the production of other organic compounds. After the reaction, the catalyst was electrochemically diregenerasikan potential reduction in very low, this means that it is highly unusual in energitikal.

The process does not improve the global warming problem properly and probably never will. "Our study purely a fundamental, and the findings will require additional work before they may be applied to the industrial sector," Bouwman said.

However, "it was remarkable that the catalyst was very special to reduce CO2 to oxygen and that the electrochemical step requires very little energy states that" the catalyst structure is almost perfectly adapted to the reaction to work, "commented Clifford P. Kubiak from the University of California, San Diego, a specialist in the conversion of CO2. Compared to the way - another way to remove CO2 from the air, changing greenhouse gases into the catalytic oxalate, efficient and selective "a little longer until the desired top level," he said.
