Manganese Hexacyanoferrate (MnHCF) and partially nickel substituted MnHCF were synthesized by simple co-precipitation method. The water content and chemical formula were obtained by TGA and MP-AES measurements, functional groups by FT-IR analysis, the crystal structure by PXRD and a local geometry by XAS-EXAFS spectroscopy. With the addition of nickel, vacancies and water content increased inside the sample. Crystal structure has changed from monoclinic to cubic. Ni disturbed the local structure of Mn, site, however, almost no change was observed in Fe site.

Abstract

Manganese Hexacyanoferrate (MnHCF) and partially nickel substituted MnHCF were synthesized by simple co-precipitation method. The water content and chemical formula were obtained by TGA and MP-AES measurements, functional groups by FT-IR analysis, the crystal structure by PXRD and a local geometry by XAS-EXAFS spectroscopy. With the addition of nickel, vacancies and water content increased inside the sample. Crystal structure has changed from monoclinic to cubic. Ni disturbed the local structure of Mn, site, however, almost no change was observed in Fe site.
