Abstract Environmental contamination by hexavalent chromium (Cr(VI)) and antibiotic drug residues pose significant challenges to public health ecosystems. This study investigates the application of CoTiO 3 /BiVO 4 @MIL-Fe(53) (CT/BV@Fe-MOF) for reduction Cr(VI) degradation tetracycline (TCL) under visible light. After grafting an iron-based metal–organic framework MIL-Fe(53) on a modified composite, photogenerated electrons could easily be transferred from BiVO /Fe-MOF species via interfacial charge transfer. UV–vis diffuse reflectance spectroscopy showed that carriers were formed in response light absorption. The effect different operating parameters, including catalyst load, pH, initial Cr(VI), TCL concentration, was systematically evaluated during photocatalytic process. CT/BV@Fe-MOF composite exhibited 98.7% efficiency (50 ppm) 97.5% towards (30 within 90 min, resulting greater than pristine , Fe-MOF materials. displayed excellent stability over six cycles, highlighting its potential practical applications. In addition, plausible pathway using LC-ESI/MS analysis, while TEST program utilized investigate toxicity products generated

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
