Synthesis of monodisperse iron oxide nanoparticles without surfactants
MetadataShow full item record
© 2014 Xiao-Chen Yang et al. Monodisperse iron oxide nanoparticles could be successfully synthesized with two kinds of precipitants through a precipitation method. As-prepared nanoparticles in the size around 10 nm with regular spherical-like shape were achieved by adjusting pH values. NaOH and NH· H were used as two precipitants for comparison. The average size of nanoparticles with NH· H precipitant got smaller and represented better dispersibility, while nanoparticles with NaOH precipitant represented better magnetic property. This work provided a simple method without using any organic solvents, organic metal salts, or surfactants which could easily obtain monodisperse nanoparticles with tunable morphology.

Precipitation of iron silicate nanoparticles in early Precambrian oceans marks Earth’s first iron ageRasmussen, Birger; Krapež, Bryan; Muhling, Janet; Suvorova, A. (2015)The early ocean was characterized by anoxic, iron-rich (ferruginous) conditions before the rise of atmospheric oxygen ~2.45 b.y. ago. A proxy for ferruginous conditions in the ancient ocean is the deposition of banded ...
