Effect of different fuels on the alumina–ceria composite powders synthesized by sol–gel auto combustion method

Physiochemical properties of combustion synthesized La0.6Sr0.4Co0.8Fe0.2O3− perovskite: A role of fuel to oxidant ratio

“…Fig. 5 shows the FT-IR spectra of LSCF powder at different ψ and calcined at 650°C for 5 h. The modes of vibration within 400-655 cm À 1 correspond to the presence of metal-oxygen bond in the perovskite structure [23,24]. The bands in this region get flattened with the increase of fuel content and merge into one another.…”

Sol–gel synthesis and characterization of Al2O3–CeO2 composite nanopowder

“…In nano-scale form, as the particle size decreases, the amount of lattice defects, such as oxygen vacancies and grain boundary increases. Moreover, high surface area increases the catalytic efficiency of these inorganics [9]. Conventional processes for synthesizing ceramic nanopowders involve mechanical synthesis [10], vapor deposition [11], co-precipitation [12], combustion [13], sol-gel [14] and other related methods.…”

Shape tailored green synthesis of CeO 2 :Ho 3+ nanopowders, its structural, photoluminescence and gamma radiation sensing properties

“…However, it remains a nontrivial task to fabricate the nanocrystals with unique morphologies in a tunable way using a simple method, especially for the cerium compounds. For example, the well-defined CeO 2 nanostructures with a variety of morphologies have been successfully synthesized through a variety of complicated methods [18][19][20].…”
