摘要：
In this research, metal-organic frameworks ZIF-8 nanoparticles, which is synthesized via the liquid phase method, exhibits the outstanding piezocatalytic performance on Rhodamine B (RhB) dye degradation under vibration. The piezocatalytic degradation ratio of RhB dye (5 mg/L) can reach ∼94.5% after undergoing 90 min vibration. ZIF-8, with the coexistence of cubic phase and monoclinic phase, confirmed from XRD, is piezoelectric in theory, which contributes to the excellent piezocatalytic performance. The main active species, which plays an important role in piezocatalytic process, are the superoxide radicals (· O2-), the positive charges (q+) and the negative charges (q-) on basis of the active species quenching experiment results. The MOF material ZIF-8 is potential in the application field of the highly piezocatalytic dye wastewater degradation under vibration. © 2021 Elsevier B.V.
