Combustion Synthesis of Fe-Incorporated SnO₂Nanoparticles Using Organometallic Precursor Combination

Abstract

Synthesis of nanomaterials within flames has been demonstrated as a highly scalable and versatile approach for obtaining a variety of nanoparticles with respect to their chemistry, composition, size, morphology, and dimensionality. Its applicability can be amplified by exploring new material systems and providing further control over the particle characteristics. This study focused on iron-incorporated SnO2nanoparticles generated using an inverse coflow diffusion flame burner that supported a near-stoichiometric methane-air combustion. A liquid organometallic precursor solution of Sn(CH3)4and Fe(CO)5was used to produce 11–14 nm nanocrystalline particles. Synthesized particles were analyzed using TEM, XRD, and XEDS to characterize for size and composition. A flame temperature field was obtained to map particle evolution within the flame. A range of conditions and parameters were studied to specifically generate targeted particles. The study augments related research towards increasing the production potential of combustion synthesis.

Mn Ion substituted CeO2Nano spheres for Low Temperature CO Oxidation: The Promoting Effect of Mn Ions

“…Six spherical shaped particles are surrounded by one particles with hexagonal shape which is shown in Figure (b). The selected area of TEM image has 318 particles, those particle size distribution was shown in Figure (c), confirms relatively narrow distribution . The selective area electron diffraction (SAED) pattern [Figure (d)] of Ce 1‐x Mn x O 2‐δ (X=0.2) complements XRD data.…”

Grain boundary effect on structural, optical, and electrical properties of sol–gel synthesized Fe-doped SnO2 nanoparticles

“…[21] Doping with transition metal is found to have a deep influence on the properties of the tin oxide. [22][23][24][25][26][27][28] One of the most commonly observed consequence of doping is the segregation of dopants or impurities at the grain boundaries. [29] This results in the segregation of defects at the grain boundaries which in turn can affect material properties.…”
