Catalyzed CO oxidation: A newly designed high-pressure flow cell is utilized to study CO oxidation on Pt nanoparticles in situ by simultaneous quadrupole mass spectrometry and high-pressure X-ray photoelectron spectroscopy. The spectroscopy data show that the active catalyst consists of metallic Pt with both chemisorbed O and patches/shell of surface oxides.
