This study presents a OH⁻ concentration-regulated one-step hydrothermal synthesis of a novel SrBi₄Ti₄O₁₅/BiOCl heterojunction for efficient antibiotic degradation. Precise control of alkaline conditions enabled the in-situ generation of Ti–Cl bonds at the heterointerface, with their presence and nature further corroborated by Raman and XPS analyses. The SBTO/BOC heterojunction demonstrated significantly enhanced charge separation, achieving a 91.5% tetracycline degradation rate under illumination, outperforming pure BiOCl (71.9%) and SBTO (54.8%). Radical trapping and EPR studies identified ^•O₂⁻ and ^•OH as the primary reactive species. The catalyst exhibited robust stability, broad pH tolerance, and resistance to ionic interference. Tetracycline degradation efficiency further improves under combined light and ultrasonic irradiation, leveraging piezoelectric polarization to boost charge separation. LC-MS analysis revealed reduced toxicity of degradation intermediates. This work highlights the strategic role of OH⁻-mediated interface engineering in designing efficient ferroelectric heterojunctions for wastewater remediation.
