Studying Cerium With Cosmic

Caption

At the COSMIC Microscopy beamline, researchers probed the oxidation state of the chemical element cerium using scanning transmission X-ray microscopy (STXM) under operando conditions. It was a first demonstration of this capability at COSMIC. The results confirmed how cerium particles dictated the size and locations of the reaction sites of platinum particles. In this artistic depiction, hybrid CeOX-TiO2 nanoparticles (silver spheres) are shown evenly covered with platinum and cerium pairs (yellow and blue) while conventional titanium dioxide particles are shown less densely covered with larger platinum clusters (gold).
