CO2 molecules land on the surface of the catalyst during CO2 hydrogenation. At a high pretreatment temperature, titanium atoms (brown) remain on the nickel (gold).
CO2 molecules land on the surface of the catalyst during CO2 hydrogenation. At a high pretreatment temperature, titanium atoms ( brown ) remain on the nickel ( gold ) . An international research team led by Bert Weckhuysen (Utrecht University) and Sara Bals (University of Antwerp) has shown that a promising catalyst for clearing CO2 becomes significantly more active and selective if its pretreatment is modified. The scientists visualized the mechanism underlying this concept with unparalleled precision. The results of the study appeared in the prestigious scientific journal Science on 11 May. Matteo Monai, Kellie Jenkinson and Angela Melcherts are the first authors. Cleaning up carbon dioxide or converting it into something useful is becoming increasingly common, for example in the energy and transportation sectors, where huge amounts of the greenhouse gas are emitted.
