The CO2 rejected by human activities, which is the principal element responsible main factor for global warming, could. One day, this could be easily be recycled to supply into an energy source. This is precisely what the research work byof a team from the Laboratoire d’électrochimie moléculaire (LEM)1 promises seeks to do just that achieve. The researchers scientists have developed come up with a procedure process capable ofthat can transforming greenhouse effect gas into methane, the principal component of natural gas, simply by using solar light and a molecular catalyst.
In contrast to other procedures of CO2 transformation methods used to date, the one technique developed by the chemists is much more environmentally-friendly; the reaction is carried out occurs at atmospheric temperature and pressure, and uses relies on sunlight as the only energy source, a principle that is comparable to that of photosynthesis in which plants transform CO2 using through solar energy. Additionally, the catalyst used is based on iron, an abundant, non-toxic metal. “For all these reasons, the large-scale development of our procedure system is an a aim goal that we wish want to pursue”, underlines Marc Robert, of the LEM.
For this wish to become reality come true, the researchers are now attempting to understand CO2 catalysis in the minutest detail. The first phase step of the procedure process, where CO2 is transformed into carbon monoxide, is already perfectly well-described. Moreover, the chemists have designed a device dedicated uniquely solely to this reaction, which won earned Marc Robert and his colleagues Jean-Michel Savéant and Cyrille Costentin the Air Liquide Air company’s prize for the challenge of group’s “Essential Mmolecules Challenge”. Carbon monoxide is a key raw material that is important for the chemical industry in the short-term. The LEM team plans to develop a reactor that is capable of able to producinge this gas in large quantities.
