Abstract Mixing of industrial waste water effluents with fresh reservoirs without prior removal pollutants is major cause concern for healthy aquatic life. Therefore, remediation in by suitable photocatalyst an interesting area to alleviate pollution. Many have been designed recently but there still gap synthesize the optimized energy bandgap material high efficiency degrade organic dyes shortest time. Hence, sunlight driven doped ZnO materials, i.e., Zn 1−x Fe x O (x = 0, 0.02, 0.04, and 0.06) photocatalysts were designed. The effect concentration on structural, morphological, optical, electrical, magnetic properties was studied. hexagon-shaped wurtzite structure NPs verified x-ray Diffraction calculated average crystallite size ∼25 nm which vary dopant concentration. EDX results showed 100% purity samples. With increase concentration, a slight decrease (3.10 3.02 eV) observed. FTIR spectra presence Zn-O Fe-O bonds doping also variation dielectric ac conductivity Hysteresis curves plotted exhibit room temperature ferromagnetic (RTFM) behavior. 2 mol% sample retained highest saturation magnetization 11.2 emu g −1 . All samples above 90% degradation methylene blue just 90 min exposure sunlight.
