Many of the things that surround us are chemically derived from fossil gas and oil—from washing powders to phones to pharmaceuticals. As such, chemistry contributes to CO2 emissions in the same way as, for example, flying does.
"It is a problem that the fuels and chemicals we use to produce plastics and pharmaceuticals today are based on oil and gas. We need to find alternative chemical reactions and new catalysis based on renewable energy sources to secure a green transition. High-entropy alloys open up new avenues for what we can achieve," says University of Copenhagen chemistry professor Jan Rossmeisl.
Researchers - Rossmeisl - Kroner - Grant - Danish
Along with three other researchers, Rossmeisl has just received a 61 million kroner grant from the Danish National Research Foundation to establish a center that will study catalysis on high-entropy alloys.
High-entropy alloys consist of five or more different elements that can be randomly combined in millions of possible ways. Theoretical evidence suggests that some of these combinations may espouse optimal properties to act as catalysts. Now, researchers would like to look into whether theoretical promise can be translated into practice to produce high-entropy alloys that work as effective catalysts.
