| Abstract Scope |
Iron oxide nanoparticles (IONPs) are of high interest given their superparamagnetic properties, which make them suitable for applications such as catalysis and magnetic imaging. Gas-phase syntheses are scalable and cost-effective processes, where the inlet gas reactant decomposes into atoms in the reaction zone, nucleating and growing to form nanoparticles. This work aims to study the synthesis of IONPs using a gas-phase flame reactor. The reactor was equipped with a matrix burner that allows for non-premixed and premixed flames, although only non-premixed methane/oxygen pilot flames were used. The gas-phase IONPs precursor used was iron pentacarbonyl. The IONPs were harvested at the downstream filter, and were characterized using TEM, XRD, Raman Spectroscopy, and XPS. The IONPs present a mixture of different oxidation states and a narrow size distribution. Future work will involve e.g., adding an inline coating to create a silica shell around the single IONPs to avoid further oxidation. |
