Recycle carbone dioxide more efficiently and cleanly?

A collaboration involving the SB2SM (I2BC@Saclay) works on bio-inspired processes to recycle carbon dioxide (CO2), a major environmental problem. Researchers have  formulated a new catalyzer very efficient for reducing CO2 in water. The study has been published in Chemical Communications.

In this study researchers from the Institut de Chimie Moléculaire et des Matériaux d'Orsay (ICMMO1), the Laboratory of fundamental Mechanisms in Bioenergetics (LMB/SB2SM) and from the Institut des sciences chimiques de Rennes (ISCR2report a strategy to attach methylimidazolium fragments as ionic liquid units on an established iron porphyrin catalyst for the selective reduction of CO2 to CO. Importantly, they found that the tetra-methylimidazolium containing porphyrin exhibits an exalted electrocatalytic activity at low overpotential in water precluding the need for an external proton donor.
