Photocatalytic activity of spinel ferrites CoxFe3-xO4 (0.25 < x < 1) obtained by treatment contact low-temperature non-equilibrium plasma
Abstract
CoxFe3-xO4 (0.25 < x < 1) spinel ferrite nanocrystalline powder was synthesized by co-precipitation method and low-temperature contact nonequilibrium plasma treatment. Structural characterization of the samples was performed using powder X-ray diffraction. The results show the presence of mixed-type spinel with a cubic structure. It is established that the distribution of cations and structural parameters strongly depends on the ratio of cations. It is determined that the photocatalytic activity in the decomposition reaction 4-nitrophenol decreases with increasing x.
