Microwave-assisted flow synthesis of multicore iron oxide nanoparticles 2022 Access copy available to the general public Unrestricted Coprecipitation is by far the most common synthesis method for iron oxide nanoparticles (IONPs). However, reproducibility and scalability represent a major challenge. Therefore, innovative processes for scalable production of IONPs are highly sought after. Here, we explored the combination of microwave heating with a flow reactor producing IONPs through coprecipitation. The synthesis was initially studied in a well-characterised microwave-heated flow system, enabling the synthesis of multicore IONPs, with control over both the single core size and the multicore hydrodynamic diameter. The effect of residence time and microwave power was investigated, enabling the synthesis of multicore nanostructures with hydrodynamic diameter between ∼35 and 70 nm, with single core size of 3–5 nm. Compared to particles produced under conventional heating, similar single core sizes were observed, though with smaller hydrodynamic diameters. The process comprised of the initial IONP coprecipitation followed by the addition of the stabiliser (citric acid and dextran). The ability of precisely controlling the stabiliser addition time (distinctive of flow reactors), contributed to the synthesis reproducibility. Finally, scale-up by increasing the reactor length and using a different microwave cavity was demonstrated, producing particles of similar structure as those from the small scale system, with a throughput of 3.3 g/h. info:eu-repo/grantAgreement/EC/H2020/721290/EU/European Training Network for Continuous Sonication and Microwave Reactors/COSMIC This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 721290-COSMIC info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.3 2022 ENGINEERING, CHEMICAL 45 / 141 = 0.319 2022 Q2 T1 ENERGY & FUELS 64 / 119 = 0.538 2022 Q3 T2 0.744 2022 Industrial and Manufacturing Engineering 2022 Q1 Chemistry (miscellaneous) 2022 Q1 Chemical Engineering (miscellaneous) 2022 Q1 Process Chemistry and Technology 2022 Q2 Energy Engineering and Power Technology 2022 Q2 6.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Besenhard, M.O.
