Abstract The piezoelectric effect is employed to enhance the photocatalytic process by enabling efficient utilization of photogenerated electrons and holes. In this study, a defect‐engineered Na–Sm bimetal‐regulated layered ferroelectric material, SrBi 2 Nb O 9 , synthesized using molten salt process, exhibits excellent piezo‐photocatalytic performance in synergistic removal uranium [U(VI)] tetracycline (TC) from wastewater. incorporation Sm dopant creates an intermediate band structure, while Na doping introduces empty orbitals into conduction band, thereby enhancing electrical conductivity, improving electron mobility, supplying sufficient promote catalytic reactions. Moreover, induces additional internal electric field, which combines embedded field along b ‐axis with polarization ‐axis. This combined enhances anisotropic migration holes, facilitating their spatial separation. doped can simultaneously remove 98% U(VI) degrade 99% TC. Furthermore, enhancement observed between reduction TC oxidation reactions, rate constant being 1.2 times higher than that individual system. work presents innovative strategy for designing catalysts able pollutants optimize redox

Constructing a heterostructure is an effective strategy for improving piezocatalytic performance. Here, Bi5Ti3FeO15/BiOCl heterostructured nanocomposites were synthesized to enhance the performance by synergy of oxygen vacancy and heterojunction. As expected, optimized exhibited superior activity toward organic pollutant degradation compared Bi5Ti3FeO15 BiOCl. Under ultrasound vibration, rhodamine B (RhB) was degraded 96% in 20 min, mixed dyes 97% within 30 min Bi5Ti3FeO15/BiOCl, efficiencies higher than numerous reported piezocatalysts. The catalyst also had efficient removal capability bisphenol A, tetracycline hydrochloride, phenol. In addition, RhB, hydrochloride efficiently decomposed under magnetic stirring, indicating that harvesting low-frequency mechanical energy. construction combined merits band structure, which enhanced absorption dyes, oxygen, OH–, improved separation efficiency carriers, promoted formation radicals, activity. This study not only shed light on design piezocatalyst but demonstrated using energy, proved be promising degrading pollutants wastewater.
