heterojunctions enable efficient charge carrier separation
while preserving strong redox ability, making them a research hotspot
in photocatalysis. 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.
