Nitrous oxide - ISCR highlighted @CNRS Chimie news

Upgrading nitrous oxide through an eco-responsible photocatalytic process

"Anything except hilarious for the climate, nitrous oxide (N2O) is the third most important greenhouse gas. Mainly produced by our agricultural and industrial activities, it's becoming a worrying waste product. Hence the idea of recycling it! Scientists at CNRS Chimie have developed an eco-responsible photocatalytic process that enables this molecule to be used to produce products of interest for the fine chemicals industry.

Nitrous oxide (N2O), also known as laughing gas, is a misnomer when it comes to the climate. Emissions of this gas into the atmosphere, mainly from our agricultural and industrial activities, are constantly increasing. With a warming power 300 times greater than carbon dioxide (CO2) and a lifespan of 120 years, it has become a major contributor to global warming and ozone depletion. ...

To overcome this barrier, chemists at the Rennes Institute of Chemical Sciences (CNRS/Université Rennes/ENSCR/INSA Rennes) have developed a silver-based catalyst supported on titanium dioxide using an easy and rapid photodeposition method. This material proved effective in specifically activating the nitrous oxide molecule under UV irradiation. ..."
