Carbon dioxide fixation and reduction by phosphine-free iron catalysts

In search of green sustainable chemistry there are different objectives to move forward in our quest to improve the world surrounding us. Here, in this contribution a collaborative study between the experimental group of Prof. Jean Luc Renaud (Univ. Normandy, France) and Dr. Albert Poater (IQCC) for the complementary computational part is reported. They have been able to achieve not only to find a catalyst capable of fixing CO2, but also observed that it is inexpensive, non-toxic, not based on noble metals, and furthermore, dealing with water as a solvent. Iron, the most abundant metal catalyst of the Earth’s layer has been employed.  Overall, a highly efficient, stable, phosphine-free, and easy-to-synthesize iron catalyst system for the reduction of CO2, hydrogenocarbonate, and carbonate in pure water is reported. This paper was published in ACS Catalysis recently.
