| Description | Microwave plasma synthesis is attractive way to produce nanostructured materials. Here we present synthesis of iron oxide nanoparticles in atmospheric and low pressure microwave discharges by decomposition of iron pentacarbonyl. In microwave plasma torch at atmospheric pressure crystalline phase of synthesized iron oxide nanoparticles could be purposely controlled by amount of O2 flow in Ar/Fe(CO)5/O2 mixture. We were able to prepare high purity maghemite samples and also samples with high content (up to 30 percent) of rare epsilon-Fe2O3 phase. Low pressure surface wave discharge was used for synthesis of magnetite and maghemite samples and their functionalization was studied. Prepared nanoparticles were used in carbon nanotube growth, photoelectrochemical studies and labeling of stem cells. |
