摘要：

X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy (UPS) were performed on as-received analytical grade Co3O4 nanoparticles (<50 nm). Co3O4 has proven to be an extremely useful material for a wide variety of applications. This report provides a detailed photoelectron spectroscopy investigation of Co3O4 to aid with identification from other cobalt oxides, hydroxides, and oxyhydroxides. In addition to the survey scan, detailed charge-corrected scans for Co 2s, Co 2p, Co 3s, Co 3p, O 1s, O 2s, and C 1s surface photoelectron signals are reported. The valence states were analyzed using UPS.
