this paper, we report a new modified solution combustion synthesis
technique for one-step production of metallic Co nanoparticles. 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-assisted foam and hexamethylenetetramine
as a fuel allows us to produce metallic Co nanoparticles with the
broad size distribution (∼5–40 nm), high coercivity
(370 Oe), and high value of saturation magnetization (137 emu/g) by
the one-step solution combustion synthesis under normal air atmosphere
without any post reduction.
