Novel preparation of ultrafine MnCo_(1.75)Fe_(0.25)O_4 nanostructures for the photodegradation of Acid Red 88

摘要

For the first time, ultrafine MnCo_(1.75)Fe_(0.25)O_4 nanostructures were prepared via a novel coprecipita-tion-calcination route by using tetraethylenepentamine (tepa) and SDBS as precipitating agent and surfactant, respectively. Results of this study show that particle size and morphology of the MnCo_(1.75)Fe_(0.25)O_4 samples can be controlled by setting main reaction parameters such as reaction temperature, surfactant type and calcination temperature. The as-prepared MnCo_(1.75)Fe_(0.25)O_4 nanostructures were characterized by EDX, TEM, FESEM, VSM, FT-IR, XRD and UV-Vis analysis. The photocatalytic degradation of the acid red 88 dye as water pollutant was performed to examine the photocatalytic performance of as-prepared MnCo_(1.75)Fe_(0.25)O_4 nanostructures.
