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.
