Efficiently enhancing the photocatalytic activity of graphite carbon nitride (g-C3N4), a promising candidate for pollutants degradation, is great importance but remains challenge. Herein, bismuth oxide (Bi2O3) and layered double oxides (i.e. LDO) were applied to improve performance g-C3N4 by constructing ternary CoFe LDO/α-Bi2O3/g-C3N4 heterostructure. Physicochemical characterization results indicate that exhibits large surface area, competitive visible-light harvesting ability effective separation transfer efficiency photogenerated carriers. Thus, demonstrates excellent Tetracycline (TC) achieving approximately 90% degradation within 60 min, its apparent reaction rate (about 0.03919 min−1) 1.78, 1.84 9.9 times higher than LDO/g-C3N4, α-Bi2O3/g-C3N4 g-C3N4, respectively. The major active free radicals, namely •O2− h+, are largely responsible TC, as demonstrated radical trapping tests electron spin resource (ESR) measurements. feasible mechanism degrading TC heterostructure tentatively proposed.
