[1] Solution combustion synthesis of copper nanopowders: The fuel effect / K. B. Podbolotov, A. A. Khort, A. B. Tarasov et al. // Combustion Science and Technology. — 2017. Pure copper nanoparticles have previously been successfully produced by different combustion methods, but most of them require the usage of an inert atmosphere (N2, Ar) during synthesis process or the usage of addition post reducing of metal oxides. In this paper, novel modification of solution combustion synthesis technique for one-step metallic Cu nanoparticles preparation was developed. The main unique feature of our approach is the use of microwave assisted foam preparation. Also, the effect of different types of fuels (urea, citric acid, glycine and hexamethylenetetramine) on the combustion process and characteristics of resultant solid products were investigated. It was shown that the combination of microwave assistant foam preparation and using of hexamethylenetetramine as a fuel allows producing pure metallic Cu nanoparticles (∼67 nm) by one-step solution combustion synthesis under normal air atmosphere without any post reduction.
