Morphological, microstructural and photocatalytic characterization of undoped and Ni, Co doped Fe2O3 particles synthesized by sonochemical method

In this study, an abundant and eco-friendly photocatalytic material, Fe2O3 particles were synthesized by sonochemical method. Morphological microstructural investigations of undoped Ni, Co-doped performed. The effect particle morphology microstructure on its performance was further investigated. Comparative studies for evaluating crystallite sizes conducted Williamson-Hall (W-H) method modified Debye-Scherrer (MDS). Crystallite lattice strains induced process parameters calculated W-H based uniform deformation model (UDM). the powders in range 200 nm 76 analysis. addition to structural investigation, dislocation density Williamson-Smallman relation. Afterwards, investigated detail. photodegradation methylene blue solutions presence light 20 min with samples 3,4, 5 0.937, 0.896, 0.855, respectively. Moreover, solution sample 15, 30, 45 0.9, 0.828, 0.757, A activity 24.25% has been observed under optimum conditions time interval min.
