Diameter and Aggregation Controlled Preparation by Solvothermal Synthesis of Ultra-small Particles CuFe$_2$O$_4$

Abstract

Copper ferrite nanoparticles have catalytic activity for hydrogen peroxide, which can be used in many fields. This characteristic comes from the physical properties of matters at nanometer scale. Thus, controlling the size and aggregation of nanoparticles during the synthesis is one of the ways to obtain target performance. In this article, a kind of ultra-small nano particle CuFe$_2$O$_4$ with uniform morphology was prepared by solvothermal synthesis. The effects of solvent, reactant molar ratio, reaction temperature, surfactant and reaction time on the yield of CuFe$_2$O$_4$, size and morphology of nano particles were investigated under different synthesis conditions. XRD, TEM, EDS were used to analysis the materials, and the physical properties of the products were analyzed. An optimized solvothermal synthesis scheme was proposed.
