High-energy-resolution fluorescence-detected Xray absorption spectroscopy (HERFD-XAS) has been applied to study the chemical state of similar to 1.2 nm size-selected Pt nanoparticles (NPs) in an electrochemical environment under potential control. Spectral features due to chemisorbed hydrogen, chemisorbed O/OH, and platinum oxides can be distinguished with increasing potential. Pt electro-oxidation follows two competitive pathways involving both oxide formation and Pt dissolution.
