Recent developments in the formation and structure of tin–iron oxides by laser pyrolysis

Combustion Synthesis of Fe-Incorporated SnO2Nanoparticles Using Organometallic Precursor Combination

“…With respect to the varying concentration of IPC in TMT, neither the crystallite size nor the primary particle sizes indicated any significant changes in sizes. This result is in contrast with other studies involving changing iron dopant concentration in SnO 2 that have observed a decrease in particle size as concentrations of iron increases [11,13,32,39]. On the other hand, a similar trend was exhibited by Liu and coworkers where the increase in dopant concentration yielded larger crystallite sizes [23].…”

“…The eventual encapsulation of SnO 2 was supported by the combination of XEDS and HRTEM analysis on the particles as a function of Fe concentration. The work by Castro et al substantiates the observations on combustion-synthesized powders presented here and results of other similar studies [15,32].…”

“…Subsequent XRD analyses of the products from 10 at% IPC yielded identical results when compared to the 2.5 at% IPC-only cassiterite-phase tin dioxide was identified while no peaks could be attributed to any iron or iron based compound. These results are in agreement with the recently published work by Alexandrescu and co-workers [32] using IPC and TMT as precursors with laser pyrolysis, where no iron compounds were identified. Melghit and Bouziane [15] also demonstrated the absence of iron-based compounds in tin dioxide powders and attributed the outcome to Fe atoms substituting Sn in the lattice with comparable iron concentrations to this study.…”

Highly magnetic Fe2O3 nanoparticles synthesized by laser pyrolysis used for biological and heat transfer applications

“…The synthesis of iron oxide nanopowders was performed using a modified version of the previously described laser pyrolysis protocol [11,12]. An O 2 -Ar mixture (richer in oxygen than air) was used in combination with C 2 H 4 and Fe(CO) 5 vapors forming the reactive mixture.…”

Nanostructured thin film of iron tin oxide by aerosol assisted chemical vapour deposition using a new ferrocene containing heterobimetallic complex as single-source precursor

“…Iron doped tin oxides have been reported using different techniques, viz. the sol-gel technique [17], pulsed laser pyrolysis deposition, co-precipitation [18], solvothermal reduction [19], ball milling [20], combustion [21], and atomic layer deposition [22]. The usefulness of heterobimetallic coordination complexes as single source precursors for the formation of mixed-metal oxides thin films is relatively less explored [23].…”
