“…The present method might be explained as a combination of chemical solgel and combustion process, i.e., auto-combustion synthesis 14 caused by rapid boiling of the solution. In the present scheme shown in Figure 1, preheating to 80°C helps in the formation of the sol 15 and viscous liquid formed during rapid boiling.…”

The present paper reports extremely efficient and versatile route for the synthesis of cubic copper ferrite (CuFe 2 O 4 ) powder, which is promising for many interesting applications such as Li-ion storage, gas sensors, catalysts, and magnetic devices. The technique uses ethylene glycol (EG) as a solvent of Cu(NO 3 ) 2 and Fe(NO 3 ) 3 . It has been found that crystalline CuFe 2 O 4 powder is obtained by rapid boiling of the solution and spontaneous combustion. This time a hotplate (300°C) was used, and the time required for obtaining 100 mg of the final product from 50 mL solution was only 15 min. The obtained CuFe 2 O 4 powder has a cubic structure, while the tetragonal phase is more likely to be obtained in the ordinary process. The size of the crystal is rather small, mainly because of the low-temperature process. The technique is promising, because it is rapid and uses only one simple pass. For comparison, much slower drying (overnight at 100°C) of the same solution has been also studied. It has been found that tetragonal phase CuFe 2 O 4 is formed by subsequent heating the dried materials up to 1000°C.

“…Among wet chemical methods, the nitrate-citrate combustion synthesis is the most attractive one because it is simple, fast, and cheap. It is an efficient procedure for synthetize pure, crystalline and nanosized powder of perovskite oxides with designed stoichiometry [16][17][18][19]. Indeed, cation are chelated by citrate anion and are homogenously distributed at a molecular level providing stoichiometric materials.…”

Catalysis science offers to combustion technology significant opportunity to increase the fuel efficiency by lowering the internal temperature gradients and reduce the environmental impact by lowering local peak temperature and, consequently, thermodynamically inhibiting the nitrogen oxides formation. Alternative catalytic materials are transition metals oxide, including complex oxides with perovskite crystalline structure. The aim of this work is to synthetize lanthanum ferrite perovskites with lanthanum ions partially substituted by strontium ions in order to study the substitution effects on structural properties and redox activity of the original oxide. Lanthanum ferrite oxides partially substituted with different Strontium amount were synthesized by solution combustion method. The perovskite nanopowders obtained were characterized by XRD, SEM, TPR analyses for defining crystalline structure, morphology and redox properties. Finally, the catalytic activity for methane combustion was tested. The most performing catalysts was La0:6Sr0:4FeO3 having the highest oxygen vacancy concentration as revealed byTPR analysis
