The first structural, morphological and magnetic property studies on spinel nickel cobaltite nanoparticles synthesized from non-standard reagents

“…12,16 In this context, cobaltite nanomaterials with a spinel structure have received much attention and have gained recognition from worldwide researchers due to their strong physicochemical properties and high potential in the field of electrochemistry. 15,17–19…”

“…On the one hand, the used salt act as a template or reaction medium for the formation of specific nanostructures. 17,18,26 On the other hand, it is favorable for the molten salt process to create abundant defects in catalysts, thus promoting the electrocatalytic processes. 17,18,26 We explored the effects of the synthetization parameters on the crystallization of NiCo 2 O 4 , such as temperature or annealing duration, and we studied the morphological and magnetic behaviors of NiCo 2 O 4 using various characterization techniques.…”

“…12,16 In this context, cobaltite nanomaterials with a spinel structure have received much attention and have gained recognition from worldwide researchers due to their strong physicochemical properties and high potential in the field of electrochemistry. 15,[17][18][19] One of the interesting nanomaterials in the cobaltite material family is NiCo 2 O 4 . Nickel cobaltite is very interesting due to its natural abundance, low toxicity, low cost, higher catalytic activity, ferromagnetic properties and diverse nanostructures that are practical for better supercapacitive characteristics and widely used in electrochemical sensors, metal-air batteries, water splitting, supercapacitor, electrocatalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline media.…”

Molten salt synthesis of LiMn 1 . 2 Ni 0 . 3 Cr 0 . 1 Co 0

“…For that various doped LiM x Mn 2-x O 4 (M Al, Cr, Nd, Y, Ni…) materials were synthesized, and the results show the enhancement of the electrochemical performance. [18][19][20][21][22][23] Herein for the first time, we synthesized a multidoped LiMn 2 O 4 by molten salts method using a nonstandard metallurgical grade reagent, because recently, we have been able to synthetize the phases, LiCo 2 O 4 , 24 MnCo 2 O 4 , 25 and Ni 0.5 Zn 0.5 Fe 2 O 4 26 of spinel structure from nonstandard reagent, and we have shown that the molten salt process is the most suitable for obtaining high-purity phase in the case of compound of spinel structure, as confirmed by Santosh et al 27 In addition, this study shows the possibility to synthesize a pure phase of spinel cathode material from low-cost reagent which opens the door to develop low-cost cathode material for Li-ion batteries. The crystallinity and the purity of the obtained powder were investigated using XRD and FT-IR techniques, the morphology and the electrochemical performance of the obtained multidoped LiMn 2 O 4 were also investigated.…”
