One-Pot Synthesis of Oxidation-Resistant Silica-Coated Iron Nanoparticles via Ultrasonically Assisted Citrate Modification

Abstract This study presents a facile, one-pot aqueous coating strategy to synthesize oxidation-resistant silica-coated iron (Fe/SiO2) core–shell nanoparticles under ambient conditions. Citrate-mediated reduction produced metallic Fe cores, with citrate ions and a thin native sur...
