摘要: The multiferroic materials Bi0.95Er0.05Fe1−xCox O3 (x = 0, 0.01, 0.03, and 0.05) are synthesized by solvothermal method. X-ray diffraction pattern is used to confirm the formation of rhombohedral crystal structure. TEM images show agglomerated nanosize particles. With concentration Co, a red shift observed in charge transfer transition O2p-Fe3d band gap decreases. At higher saturation magnetization enhances coercivity also varies with Co. photocatalytic degradation methylene blue evaluated under visible light assistance H2O2. increase Co concentration, activity main species responsible for found out using scavengers like ammonium oxalate, silver nitrate, p-benzoquinone, tert-butyl-alcohol. possible mechanism dye explained.
