Abstract
Carbon-bearing Ni(II)-ferrite (CBNF) was prepared by repeated decompos ition of CO2 on H-2-reduced Ni(II)-ferrite. The material was also char acterized by Mossbauer spectra, XRD and chemical analysis. A peculiar amorphous surface layer composed of carbon, divalent transition metals and oxide ions (CIO layer) was found to be synthesized on the surface of the CBNF. Deposited carbon on the CBNF was characterized using X-r ay photoelectron spectroscopy. About 70% of deposited carbon was assig ned to graphite.
