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.
Unveiling the properties of a versatile 2D material for energy storage and production applications
Researchers from Linköping University and MAX IV have determined the detailed surface atomic arrangement of inherently formed termination species in an important class of two-dimensional materials known as MXene. The results have implications for the use of the material in energy storage and production applications.
Designing a Model Catalyst for Large-Scale Biofuel Production
The future of efficient biofuel production is within reach. With measurements from MAX IV’s SPECIES beamline, a group from Lund University and RISE, Research Institutes of Sweden, has successfully developed a model catalyst that, once tuned, holds the potential to significantly improve the treatment process for the large-scale manufacture of viable biofuels from lignin. Lignin is a plant polymer only secondary in abundance to cellulose in nature.
