Iron salt solvent dissolves in the polyols solvent. The suspension is stirred and heats up to boiling point of solvent. Polyols act as reducing as well as stabilizer
Control of particle growth and prevention of interparticle aggregation and obtaining well-defined shape and control size of particles
Hydroxylation and condensation of molecular precursors in solution are known as “sol,” while evaporation of solvent to form three-dimensional network of nanoparticles is called “gel”
Control of particles size and stability of particles in sol-gel matrix
