Published: Feb. 21, 2025

Abstract Efficient separation of photogenerated charges at the surface photocatalysts is vital for achieving high photocatalytic activity. Here, a Bi/Bi 4 NbO 8 Cl heterostructure piezo‐photocatalyst with an amorphous/crystalline interface (acBi/BNC) prepared by in situ reduction using Bi as self‐sacrificial template. This ingenious design synergistically utilizes advantages structure, localized plasmon resonance effect, and piezoelectric field. The formation interfaces induces generation oxygen vacancies, subsequently lattice distortions, thus improving properties. Theoretical experimental results demonstrate that combination field promotes effective migration between bulk catalysts. Under simultaneous light ultrasound, optimal (acBi/BNC‐3) exhibit superior photodegradation efficiency tetracycline reached 80% within 5 min, reaction rate (2.78 × 10 −1 min ) 7.8 5.4 times pure (BNC) crystalline (cBi/BNC), respectively. Furthermore, piezo‐photocatalytic degradation surpasses those under individual photocatalysis piezocatalysis conditions. work provides novel rational to improve spatial charge Bi‐based catalysts prepare high‐performance piezo‐photocatalysts via engineering.
