Abstract
XPS spectra of Pt black in the as received state showed O and C impurities along with Pt. An in situ treatment by O2 and H2 increased Pt intensity and removed a part of oxygen and carbon impurities. The quasihomogeneous model was used for quantitative evaluation applying atomic sensitivity factors published in the literature (Ref. 1). Decomposition of the O 1s region indicated the presence of adsorbed O, OH, and H2O as well as CO and CO species, whereas the C 1s region could be decomposed to give Pt–C, graphite, CxHy polymer, and oxidized C entities
