Advanced Multimodal X-ray Visualization Techniques for Unraveling Catalytic Performance and Degradation Mechanisms of Metal Nanoparticles in Fuel Cells

Abstract This Account highlights the transformative advances enabled by the world-first BL36XU beamline dedicated to in situ and operando characterization of metal nanoparticles and adsorbed species in polymer electrolyte fuel cells (PEFCs). While PEFCs hold great promise for sus...

Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

ABSTRACT Despite the fact that only 2% of active sites can satisfy hydrogen oxidation reaction (HOR) activity thanks to fast kinetics, the fuel cell anode is still dependent on catalysts with large amounts of platinum (Pt). Herein, a minimal‐cost ruthenium catalyst bearing ultral...
