Title: One-step solution combustion synthesis of pure Ni nanopowders with enhanced coercivity: The fuel effect

Abstract

In this paper, we report a new modified one-step combustion synthesis technique for production of Ni metal 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 is observed that the combination of microwave assisted foam preparation and using of hexamethylenetetramine as a fuel allows producing pure ferromagnetic Ni metal nanoparticles with enhanced coercivity (78 Oe) and high value of saturation magnetization (52 emu/g) by one-step solution combustion synthesis under normal air atmosphere without any post-reduction processing. - Highlights: • The new approach in one-step SCS rote for Ni nanoparticles preparation is proposed. • Ni particles were synthesized with microwave-assistance and under air atmosphere. • The effect of different type of fuels on the combustion process was investigated. • Using of hexamethylenetetramine allows obtaining pure Ni nanoparticles. • Ni nanoparticles have enhanced coercivity and high saturation magnetization.
