Synthesis of iron oxide nanoparticles using precipitation method with different pH values

Tailored synthesis of iron oxide nanoparticles for specific applications using a statistical experimental design

“…Furthermore, the higher the value of said interrelation, the greater the saturation of the magnetization. This agrees with previous research as larger sizes of magnetite nanoparticles within the range where superparamagnetic behavior occurs exhibit greater saturation magnetization [ 24 , 29 ].

“…This study presents a clear demonstration of the reaction and formation pathways in the co-precipitation of magnetite nanoparticles. The addition of base to the iron solution resulted in the nuclei and growth of nanoparticles passing through the goethite phase before reaching the magnetite phase, corroborating previous findings [ 13 , [22] , [23] , [24] , [25] ]. In the diffractograms obtained for pH9 and pH11 it is possible to observe that the peak positions are slightly shifted towards higher 2θ values, indicating that the lattice parameter is contracted potentially due to the eventual oxidation of magnetite (This will be discussed later in this article.).…”
