The development of effi cient, recyclable, broad-spectrum photocatalysts was the primary objective in the fi eld of photocatalytic

wastewater degradation. Herein, a novel highly effi cient ternary magnetic semiconductor composite was synthesized by

integrating SrFe 12 O 19 , MoS 2 nanofl ower clusters, and SnS 2 nanofl owers using high-temperature calcination and a one-step

solvothermal method. The synthesized heterojunction nanocomposite was characterized using numerous analytical techniques,

and its photocatalytic activity was evaluated under half sunlight intensity irradiation. The integration of SnS 2 with

SrFe 12 O 19 and MoS 2 eff ectively modifi ed the crystal structure and morphology of SnS 2 nanofl owers, leading to an increase in

active sites while overcoming the signifi cant electron–hole recombination rates of the individual components. The SrFe 12 O 19 /

SnS 2 /MoS 2 composite achieved 98.69% degradation of MB dye at a suitable pH of 6 and a period of 120 min of irradiation.

Additionally, it maintained an excellent magnetic phenomena which contributed to it eff ortless to collect and reclaim from

the residual mixture. After three cycles, the MB dye degradation remained at 84.07%, demonstrating its endurance and

resilience. The scavenger test identifi ed the superoxide radical as the primary agent responsible for dye destruction. This

work provides study presents a synthesis method for highly effi cient photocatalysts using in natural visible-light that can be

recovered by simply applying an external magnetic fi eld.
