It is based on the exothermic reaction of the correspondingmetal nitrates with a reducing agent, to produce extremely fine-grained ashes that readily convertinto pure ZnFe_2O_4 with treating thermally. The composition and microstructure of the so-obtainedsamples were studied by XRD (X-ray powder diffraction), TEM (Transmission Electron Microscopy) andAFM (Atomic Force Microscopy). These results showed that the range of particle size of ZnFe_2O_4 isabout 15-25 nm. Photocatalytic activities of nanometer ZnFe_2O_4 were also evaluated by degradationof the curcumin solution.展开更多
