| Abstract: | Abstract Magnetic carbon-iron oxide nanoparticles have been synthesized using tannin, a renewable resource material, in combination with a microwave-based thermolytic process without the addition of any inert or reducing gas during the synthesis. The predominant iron oxide species present in these particles has been determined by XRD and FT-IR to be magnetite (Fe3O4). These iron oxide nanoparticles are embedded within a carbon matrix in small clusters generally ≤100 nm in size. The resulting powder is approximately 48% (w/w) magnetite, and has been characterized by magnetic susceptibility and SQUID analysis. |
