Single component semiconductor materials with piezoelectric response can promote the activation of hydrogen ions (H + ) and generation 2 under action mechanical force, but high recombination rate carriers is major obstacle to strengthen piezocatalytic efficiency. Here, a groundbreaking Bi MoO 6 -BaTiO 3 (BMO-BTO) Type-I heterojunction piezocatalyst successfully fabricated through solvothermal strategy, applied for cocatalysts-free H production reaction. Under ultrasonic vibration, BMO-0.1BTO reach up nearly 152.57 µmol/g/h, which approximately 9.33 4.47 times respect that pristine BMO (16.36 µmol/g/h) BTO (34.16 alone, respectively. Furthermore, also combined other commonly used piezocatalysts construct heterojunctions, analogous marvelous performance was attained. The enhanced be credited established built-in electric field (BIEF) in extraordinarily suppressed rates piezocarriers, rather than an increase piezoelectricity, emphatically verified series physics chemical characterizations. This study presents innovative paradigm fabricating BMO-based efficiently convert energy into energy. attributed remarkably reduced carriers, piezoelectricity. • Highly efficient BMO-BTO heterojunctions were rationally designed. owned excellent activity stability.

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.
