Bi-piezoelectric effect assisted ZnO nanorods/PVDF-HFP spongy photocatalyst for enhanced performance on degrading organic pollutant

Hydrophilic polypyrrole and g-C3N4 co-decorated ZnO nanorod arrays for stable and efficient photoelectrochemical water splitting

“…The spacing of the lattice fringes is about 0.26 nm, corresponding to the (002) plane of hexagonal ZnO. 37 Fig. 1f and g show the TEM images of a single ZnO/PC-P nanorod.…”

Piezo-Enhanced Photocatalytic Activity of the Electrospun Fibrous Magnetic PVDF/BiFeO3 Membrane

“…Polymeric ferroelectrics, which are non-toxic, biocompatible, chemically inert, flexible, and can be formed into films, offer significant benefits in this area [ 23 , 24 , 25 , 26 , 27 ]. Among them, polyvinylidene fluoride (PVDF) is a great choice as a matrix for BFO since it is possible to obtain a piezo-photocatalyst similar to those previously reported [ 28 , 29 ]. The creation of composite polymers based on BFO for various applications was reported earlier [ 30 , 31 , 32 , 33 ].…”

Piezocatalytic performance enhancement using the sandwich structure of a PVDF-HFP/graphene film

“…20,21 Recent studies have shown that inorganic piezoceramics are usually embedded in PVDF materials to obtain both excellent piezocatalysis and recyclability, such as BaTiO 3 /PVDF, 22 Ag loaded LiNbO 3 /PVDF, 23 and ZnO nanorods/PVDF-hexa-uoropropylene (HFP). 24 Moreover, graphite llers are also added to PVDF to improve piezocatalysis instead of expensive piezoceramic llers. Graphite llers have abundant functional groups and electron clouds on their surfaces, which are conducive to inducing the formation of the b phase and providing a path for the carrier transfer of PVDF polymers.…”
