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
