In Situ Fabrication of TiO<sub>2</sub>/(Bi<sub>2</sub>O<sub>3</sub>/Bi<sub>2</sub>O<sub>2.33</sub>) S‑Scheme Heterojunction with Enhanced Bifunctional Photocatalysis for CO<sub>2</sub> Reduction and Dye Removal
Listed in ZivaHub
S-scheme heterojunctions enable efficient charge carrier separation while preserving strong redox ability, making them a research hotspot in photocatalysis.
Description
This work reports a simple and novel approach to prepare TiO<sub>2</sub>/(Bi<sub>2</sub>O<sub>3</sub>/Bi<sub>2</sub>O<sub>2.33</sub>) (TBBO) heterojunctions using Ti foil as precursors via a combined hydrothermal and calcination treatment. Photocatalytic tests demonstrate that the as-prepared TBBO catalysts exhibit significantly higher activity than pristine TiO<sub>2</sub>.
TBBO-0.02 exhibits the best CO<sub>2</sub> photoreduction performance and stability, achieving a CO generation rate of 152.5 μmol·g<sup>–1</sup>·h<sup>–1</sup>, due to its abundant oxygen vacancies and efficient S-scheme heterojunction interface. Furthermore, TBBO-0.02 also displays outstanding activity in the photodegradation of methylene blue (MB), with a degradation efficiency of 95% within 70 min. This work presents a new route for the green and facile preparation of highly efficient and stable S-scheme heterojunctions.
