Facile synthesis of morphology and size-controlled α -Fe 2 O 3 and Fe 3 O 4 nano-and microstructures by hydrothermal/solvothermal process: The roles of reaction medium and urea dose
A one step method has been developed for the fabrication of hierarchical flower-like bismuth tungstate (Bi2WO6) hollow spheres via a solvothermal process.
Fe2O3 uniformly dispersed on carbon nanotubes are synthesized using facile oxidative co-polymerization of monomers followed by heat treatment to apply electrode materials for a highly sensitive H2S chemical sensor system.
Superparamagnetic iron oxide nanoparticles (SPIONs), γ-Fe2O3, with hydrophilic surfaces are fabricated in ethylene glycol solutions, without surfactant or additive, by solvothermal process from α-Fe2O3 nanoparticle as precursors. With the addition of a trace of hydrazine hydrate, the cubic phase Fe3O4 nanoparticles are obtained instead of γ-Fe2O3. The saturation magnetization value of γ-Fe2O3 nanoparticles is up to 74.3 emu/g. This study provides a low cost, safe, and universal route to serve as excellent biocompatibility magnetic core for future applications in biomedical, agriculture, and horticulture applications.
