Gram scale synthesis of superparamagnetic Fe3O4nanoparticles and fluid via a facile solvothermal route

Abstract

Herein, we report a facile solvothermal route for the gram scale synthesis of near monodisperse superparamagnetic Fe₃O₄ nanoparticles and fluid. The efficacy in generating large scale Fe₃O₄ nanoparticles arises from the interfacial hydroxyl-aided Ostwald ripening process. Uniform Fe₃O₄ nanoparticles have been obtained in a high scale (∼1.19 g per one-pot).
