Sandwich-like Hybrid Electrospun Membrane-Based Efficient Hydrogen Evolution System by the Push–Pull Double Piezoelectric Effect Driven by Water Flow

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Март 24, 2025

An efficient photocatalytic hydrogen evolution is realized by a push-pull effect from the piezoelectricity of flexible hybrid membrane introduced via water flow energy. The possesses sandwich-like structure, prepared sequentially electrospinning poly(vinylidene fluoride) (PVDF), depositing graphitic carbon nitride with Pt atoms (g-C3N4@Pt), and again PVDF. Due to piezoelectric property PVDF, deformation obtained PVDF/g-C3N4@Pt/PVDF triggers two electric fields same direction in top bottom PVDF membranes. Therefore, either electrons or holes photogenerated g-C3N4@Pt are attracted one field repelled another. This induces directional movement charge carriers, which not only eases separation but also hinders recombination. Based on this favorable finite element simulations for stress distribution membrane, position optimized. rate strongly increases 5401 μmol h-1 g-1 under flow, 240% that nanosheets. Thus, very suitable production natural aqueous environments rich solar energy, such as lakes rivers.
