AI Technical Summary
The practical application of persulfate-based photocatalysis for wastewater treatment is hindered by the lack of efficient, stable, and visible-light-active photocatalysts, particularly due to low charge carrier mobility in FeOOH and electron-hole recombination in CBO-based systems.
A cost-effective synthesis system for an FeOOH/CuBi2O4 heterostructure is developed, enabling synergistic interaction between FeOOH and CuBi2O4 to enhance charge separation and generate reactive oxygen species under visible light, with a dual mechanism involving both free radicals and non-radical species for efficient oxidative degradation.
The FeOOH/CuBi2O4 heterostructure exhibits improved photocatalytic efficiency, achieving high degradation rates of organic pollutants like rhodamine B and tetracycline hydrochloride, with enhanced stability and resistance to charge recombination, and operates via a dual mechanism of radical and non-radical pathways.
