AI Article Synopsis
- Piezocatalysis using gentle forces has potential applications in degrading pollutants, sterilization, and tissue recovery, but existing PVDF films show limited effectiveness.
- The study introduces a flexible porous film made from PVDF-HFP enhanced with α-FeO nanoparticles, which improves piezoelectric catalytic performance and increases Fenton reaction efficiency.
- The enhanced Fe/Fe cycle in the Fenton process leads to a 6.9% improvement in degradation rates, suggesting that this new piezo-Fenton film could drive advances in self-powered environmental purification technologies.
Article Abstract
Piezocatalysis driven by a gentle force possesses broad application prospects for degrading organic pollutants, sterilisation, wound healing and tissue recovery. The flexible and industrially scalable poly(vinylidene fluoride) (PVDF) film is commonly used in piezocatalysis. However, under gentle force action, PVDF composite-based piezocatalysis is poor. Herein, a flexible porous film based on poly(vinylidene fluoride)-hexafluoro propylene (PVDF-HFP) is enhanced with Fenton fillers (α-FeO nanoparticles). α-FeO nanoparticles improve the piezoelectric catalysis performance of PVDF-HFP by the β-phase enhancement and provide Fe to react with HO generated by the piezoelectric film itself, leading to an additional Fenton reaction. Meanwhile, the Fe/Fe cycle in the Fenton process accelerates under the piezoelectric field, promoting the Fenton reaction for 6.9% degradation improvement. The study on FeO/PVDF-HFP porous film with the piezo-Fenton reaction under flowing water may help promote new piezocatalysis designs with high efficiency for self-powered environmental purification.
