Co(OH)2 powder characterized by x-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS)

Abstract

X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy (UPS) were performed on as-received analytical grade Co(OH)2 powder. The presence of Co(OH)2 within renewable energy applications is important for enhancing activity. This report provides a detailed photoelectron spectroscopy investigation such that Co(OH)2 can be properly identified in a nondestructive manner. In addition to the survey scan, detailed charge corrected scans for Co 2s, Co 2p, Co 3s, Co 3p, O 1s, O2s, and C 1s surface photoelectron signals are reported. The valence states were analyzed using UPS.
