Solution combustion synthesis of single-phase bimetallic nanomaterials

Abstract

Solution combustion synthesis approach with hexamethylenetetramine/citric acid as mixed fuel was used for the synthesis of bimetallic single-phase nanomaterials in CoCu, CoNi, CoFe, and FeNi systems in the air. All obtained nanomaterials are characterized by fine crystallinity with crystallites sizes from 15 nm to 41 nm. The study shows the using mixed fuel in the synthesis approach allows obtaining CoNi and CoFe bimetallic phase, as synthesis in CoCu and FeNi systems results in obtaining split phases. Due to its higher stability in solutions the mixed fuel could be used for industrial scale-up of the solution combustion production of the polymetallic nanomaterials.
