Ammonium perrhenate characterized by XPS

Abstract

Ammonium perrhenate was characterized using x-ray photoelectron spectroscopy. The specimen is a powder purchased from Sigma Aldrich. The sample was fixed to a stainless-steel sample holder with copper 3MTM double-sided adhesive tape. Survey spectra, Re 4f, O 1s, N 1s, C 1s, Re 4d, and Na 1s core levels spectra were acquired. Results showed how the elements in the structure of ammonium perrhenate are related.
