The widespread discharge of organic dyes into the wastewater from various industrial processes has develop a major environmental apprehension in modern world. To tackle such issues, we are synthesizing novel catalyst composition, Ba1 − xCoxDyyFe12−yO19 (x = y 0.02–0.06) using sol-gel auto-combustion (SGAC) for photocatalytic eradication malachite green dye (MGD). fabricated sample show single-phase hexagonal structure. hexagonal-shaped grains seen field emission spectroscopy (FESEM) visuals prepared hexaferrites. oxidation states every element present developed specimens investigated X-ray photoelectron spectrophotometer scrutinized. specific surface area (SSA) HF1 is 3.523 m2/g, whereas band gap values co-doped barium hexaferrites found within range 1.61 to 1.75 eV. magnetic analysis indicates that increasing concentration Dy and Co, raised saturation magnetization declines coercivity. conducted evaluations reveal removal efficiencies 89.85%, 91.12%, 94.36% obtained HF1, HF2, HF3 after 90 min natural irradiation. Moreover, capability reusability synthesized assessed over series five consecutive experimental cycles. As result, this research delves at potential applications BaFe12O19 MGD applications.
