Bimetallic cobalt-platinum (CoPt) nanoparticles are drawing attention in many areas of catalysis as scientists tackle the quest to reduce precious metal content while maintaining optimum catalytic selectivity and reactivity. Researchers explored the role of Pt in Co reducing and oxidizing, and found that the catalytic properties of monometallic and bimetallic nanoparticles of Co are closely related to the oxidation state of Co.

Two Electron Holes in Hematite Facilitate Water Splitting
Hematite is a promising electrode material for solar-powered water splitting—an important reqirement for producing hydrogen fuel with zero emissions. At Beamline 7.0.1, researchers have gained a better understanding of hematite’s electronic structure through soft x-ray spectroscopy performed in situ and “operando.” Read more »
