PURPOSE: A production method of a ferrite nanoparticle cluster is provided to produce the ferrite nanoparticle cluster capable of being applied to energy, environment, bio, and catalysts using an environment-friendly and simple template-free method. CONSTITUTION: A ferrite nanoparticle cluster is a cluster of ferrite nanoparticles having an average particle diameter of 3-10 nm, and mesopores in a size of 2-50 nm is formed among the ferrite nanoparticles. Elements for the ferrite nanoparticles are two elements selected from Ni, Co, Zn, Mn, and Mg. A production method of the ferrite nanoparticle cluster comprises the following steps: dispersing hydrate with a divalent positive ion or ferrite hydrate with a trivalent positive ion in fluid glycol as a binary ferrite precursor to form primary ferrite nanoparticles; and coordinating a material with a carbo negative ion on the surface of the primary ferrite nanoparticles for applying the electrostatic repulsion. |
