Mg0.2Cu0.3Zn0.5Fe2O4 (MCZFO) nanoparticles were synthesized through co-precipitation reaction in the presence of Tween 20 and polyethylene glycol (PEG) as capping agents. The use of different capping agents resulted in nanoparticles with distinct morphologies, as confirmed by scanning electron microscopy (SEM). Magnetization of the nanoparticles was studied using vibrating sample magnetometer (VSM) analysis, which revealed the ferromagnetic behavior for the nanoparticles. The flake-like nanoparticles synthesized with tween 20 exhibited the higher coercivity value compared to that of synthesized by PEG. Both the synthesized nanoparticles possessed the strong absorption in the visible light region, which was particularly pronounced for the high light-contact surface nanoparticles synthesized using tween 20. Photocatalytic activity of the nanoparticles was assessed for degradation of acid red 88 (AR88) under 120 min visible light illumination. Also, photocatalysis of AR88 was investigated under different experimental conditions, including various amount of the loaded nanoparticles, different pH of AR88 solution, and use of Na2S2O8 and H2O2 solutions as oxidant agents. The MCZFO nanoparticles exhibited the excellent reusability at 6 successive reaction cycles.
