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.

Abstract Graphitic carbon nitride (gC 3 N 4 ) is an attractive photocatalyst for solar energy conversion due to its unique electronic structure and chemical stability. However, gC generally suffers from insufficient light absorption rapid compounding of photogenerated charges. The introduction defects atomic doping can optimize the improve carrier separation efficiency. Herein, high efficiency photocatalysis hydrogen evolution in visible achieved by S‐modified double‐deficient site strategy. Defect engineering forms abundant unsaturated sites cyano (─C≡N), which promotes strong interlayer C─N bonding interactions accelerates charge transport . S tunes semiconductors, formation C─S─C bonds optimizes electron‐transfer paths bonding, enhances light. Meanwhile,C≡N acts as electron trap capture photoexcited electrons, providing active reduction H + hydrogen. photocatalytic SDCN (1613.5 µmol g −1 h 31.5 times higher than that pristine MCN (51.2 ). situation transfer mechanism photocatalysts are investigated detail a combination experimental theoretical calculations.
