Transformation.

Transformation of CO2 into methanol with organokatalis.

In the journal Angewandte Chemical, researchers from IBN (Institute of Bioengineering and Nanotechnology) in Singapore reported that by using organokatalis, they can activate the process of CO2 into methanol safe very useful for industry and fuel cells. Organokatalis are catalysts that use non-metallic element found in organic compounds such as NHC (N-heterocyclic carbenes), for example IMF (1.3-bis-(2,4,6 trimethylphenyl) imidazolylidene is organokatalis form a stable and safe in storage.

These compounds do not have elements of toxic heavy metals and can be produced easily and cheaply. Scientists are reacting CO2 using NHC. When compared with inorganic catalysts, a toxic and unstable, NHC is very stable and even in open space that contact with oxygen. With these advantages NHC can react with CO2 in a dry room conditions.

Scientists at IBN also shows that only a small part of the NHC is needed to induce CO 2. One senior researcher IBN, Siti Nurhana Riduan, saying that their efforts can contribute to the reduction of CO2 in the environment and transform it into methanol, which can be useful for the industry and a source of fuel.

In this reaction, hydrosiline which is a combination of silica and hydrogen is added to the NHC teraktifasi by CO2 and the product of this reaction is methanol by hydrolysis process. Yugen Zhang (one of the researchers IBN) said that hydrosiline provide a source of hydrogen bonded to the reduction of CO2 in the process. Carbon dioxide is reduced efficiently by NHC that methanol can be easily obtained from this reaction.

Their previous research on the NHC has also concluded that the broad application of NHC can also be used as a powerful antioxidant that can prevent degenerative diseases and also mengkatalisa sugar into alternative energy sources. Currently, they have been applied to the production of methanol as the raw material from which the gas is very abundant on this earth .

Previous studies aimed at reducing the amount of CO2 into valuable products such as methanol also been carried out but in the study requires a high energy, slow reaction, and an unstable catalyst of transition metals.

IBN Executive Director Jackie Y. Ying, Ph.D., says that in the study, IBN has produced an innovative method of using raw materials that can reduce air pollution from CO2. This also can reduce the effects of global warming so that a solution for alternative energy in the middle of the energy crisis and the current environment.
