Abstract:This work focuses on the preparation of bimetal Fe−Cu oxalates by a co‐precipitation reaction in an aqueous solution and subsequently on their thermally induced decomposition. The formation of solid solutions of Fe−Cu oxalates with various Fe/Cu ratios was studied by energy dispersive X‐ray analysis, X‐ray powder diffraction, transmission 57Fe Mössbauer spectroscopy, and scanning electron microscopy. The results suggest that the bimetal Fe−Cu oxalate precipitated in a structure similar to β‐FeC2O4 ⋅ 2H2O. The … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
