Establishing an affordable solar-floating FeO@AR-TiO photo-Fenton catalytic system through the cyclic utilization of iron waste to de-pollute textile water contamination.

This study focuses on developing a cost-effective FeO catalyst from oilfield iron waste to create a floating heterogeneous photo-Fenton system with anatase/rutile(A/R) TiO heterophase photocatalyst (cork-FeO@AR-TiO) for treating textile pollution in sunlight. Through controlling sol-gel (SG) microwave heating technique, the A/R ratio of AR-TiO crystal is tuned (A/R ratio = 1.13 and E = 3.
