Facilitating the separation of photogenerated charges is a crucial process in photocatalytic degradation pollutants. In this study, Bi2O3/In2O3 composites were prepared using co-precipitation method and subsequently calcined at 400 ℃ for 1 h. The Mott-Schottky curves confirmed p(Bi2O3)-n(In2O3) heterojunction was yielded. Due to significant difference Fermi levels between Bi2O3 In2O3, an internal electric field established interface, with lines directed from In2O3 Bi2O3. Under illumination, excited electrons accumulated conduction band (CB) while holes gathered valence (VB) Bi2O3, promoting charge enhancing quantum efficiency. composite material exhibited highest activity when atomic percentage Bi 1:1, first-order reaction rate constant BI-1 increasing 0.0149 min−1, which 4.3 4.4 multiples higher than that pure Recycling experiments demonstrated possesses good reusability structural stability.
