Description:
A sustainable approach for the synthesis of various monodispersed spinel ferrite nanoparticles has been developed that occurs at water-toluene interface under both conventional and microwave hydrothermal conditions. This general synthesis procedure utilizes readily available and inexpensive salts as precursors and the method can be adopted for large scale synthesis of these spinel oxides. The ensuing spherical particles are in the size range 8-10 nm and they retain their morphology even on large scale synthesis. The synthesis and post-synthetic surface functionalization of nanoparticles will be described which renders them water dispersible for various applications including catalysis.
