Developments in time-resolved catalysis research opens a long-awaited opportunity to revisit catalytic reactions that have been subject to scientific debate. In this recent publication, the newly developed method has been used to settle the mechanism for carbon monoxide transformation to carbon dioxide over a platinum catalyst. The result is an important step towards optimisation of catalysts.
Researchers reveal mechanism behind artificial photosynthesis
Researchers have for the first time revealed the mechanism behind artificial photosynthesis. The study is an important step towards more efficient and tailored devices for local sustainable energy production.
Conversion of carbon dioxide into raw materials more effective with gold
Carbon dioxide, emitted mainly by combustion of fossil fuels, is harmful to the climate and the main reason for increased global warming. Diverting carbon dioxide into hydrogen carriers or chemicals such as methanol, a valuable raw material and energy carrier, is thus highly desired. Supported metal nanoparticle heterogeneous catalysts such as copper on zinc oxide is used for the catalytic conversion of carbon dioxide to methanol. Researchers have now discovered that it is possible to avoid by-products and at the same time make the process more sustainable by adding a small amount of gold to the catalyst.
Size of support particles is key to catalytic converter efficiency
In a study conducted at MAX IV and other European synchrotrons, researchers from the Netherlands and Belgium show that the catalytic activity of highly distributed palladium depends on the size of the cerium dioxide support particles. Optimising particle size can lead to a more effective conversion of toxic carbon monoxide exhaust even in challenging cold start conditions. The study was published in the journal SCIENCE.
