Researchers at our laboratory undertook a study of the active site and of the reactivity of the nitrous oxide reductase by means of a bio-inspired approach. They have been able to synthesize an artificial site of this enzyme, which proved to reactive towards N2O, as reflected in the production of N2. This is the first compound of this type with such activity. Change the structure of that bio-inspired complex in order to increase its catalytic activity would be an asset in the cleanup of N2O, a major greenhouse pollutant and destructive of the ozone layer.
