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.

以六亚甲基四胺/柠檬酸为混合燃料的固溶燃烧合成方法被用于在空气中的CoCu，CoNi，CoFe和FeNi系统中合成双金属单相纳米材料。所有获得的纳米材料的特征在于具有15nm至41nm的微晶尺寸的细结晶度。研究表明，在合成方法中使用混合燃料可以获得CoNi和CoFe双金属相，因为在CoCu和FeNi系统中进行合成可以得到分裂相。由于其在溶液中的较高稳定性，混合燃料可用于工业上扩大多金属纳米材料的溶液燃烧生产。
