Abstract

A fuel-based solution combustion method was used to synthesize Sr-substituted copper ferrites [Cu1−xSr xFe2O4 (x = 0.00, 0.25, 0.50, 0.75, 1.00)]. X-ray diffraction (XRD) pattern demonstrates that CuFe2O4 has a tetragonal structure and SrFe2O4 a cubic structure and the formation of particles of spherical and needle-like structures was observed using scanning electron microscopy (SEM). The magnetic behavior was investigated through a vibrating sample magnetometer (VSM) at room temperature under an applied magnetic field ranging from − 20 kOe to + 20 kOe. Based on the M–H hysteresis loop, the soft-ferrite nature of the samples was observed. The synthesized samples were investigated for adsorption and photocatalysis in the degradation of textile dyes malachite green, crystal violet, and congo red. Compared to other compositions, SrFe2O4 demonstrated comparatively better adsorption and photocatalytic efficiency.
