The quenching process is investigated to modulate domain structures behaviors in three ceramic compositions: lead zirconate titanate with a 75/25 zirconium titanium ratio (75/25PZT), Mn-doped (Mn-75/25PZT) and Nb-doped (Nb-75/25PZT). Piezoresponse force microscopy (PFM) demonstrates a transformation of domain structures from micron to nanoscale, accompanied by increased domain walls (DWs) density. In-situ Raman spectroscopy detects a softening of the E (TO1) vibration mode after quenching, indicating lower DWs energy density and higher internal stress. Furthermore, both 75/25PZT and Mn-75/25PZT demonstrate the release of pinched hysteresis loops, coupled with substantial enhancements in piezoelectric coefficients of 36 % and 37 %, respectively. Additionally, both reversible and irreversible dielectric responses are augmented through quenching. This investigation provides detailed insights into the evolution of domains during the quenching process in these ceramic systems.

Vat photopolymerization (VPP) is extensively employed in rapidly processing complex ceramic components owing to its efficiency and high-precision process attributes. However, the significant refractive index of Pb (Zr, Ti) O 3 (PZT)piezoelectric ceramic powder presents challenges for VPP in printing high-precision and complex PZT ceramic components. This article proposes a design strategy for a multi-component functional composite resin with high stability and curing strength. Through optimized resin composition regulation, the single-layer curing thickness of PZT slurry improves from 48 μm to 75 μm (56.25% enhancement), while achieving a 97.72% curing degree from an initial 56.76%. The resultant PZT ceramics exhibit excellent interlayer bonding and high relative density of 98.26%, and the piezoelectric coefficient can reach up to 452 pC/N. Finally, the PZT-based triply periodic minimal surface (TPMS) piezoelectric sensor is successfully fabricated, which demonstrates excellent force-to-electricity conversion capability. This study provides valuable insights for the VPP processing of other non-oxide ceramics.

Recently, we proposed a new approach (Li+–Al3+ ionic pairs doping) to enhance the piezoelectric properties of BaTiO3 ceramic. Here we sequentially prove that Li+ and Al3+ can also enhance the piezoelectric properties of PbZr0.52Ti0.48O3 (PZT) ceramic. The X-ray diffraction results demonstrate the optimized distribution of Li+–Al3+ ionic pairs parallel to the [001] direction in the doped ceramics, as same as the results in BaTiO3-based ceramic. The doped ceramics exhibit constricted hysteresis loops, which is associated with the restoring force of Li+–Al3+ ionic pairs as a result of the Coulomb force between Li+ and Al3+ ions. The results show that the piezoelectric properties and corresponding temperature stability of the doped ceramics were enhanced significantly. The analysis and conclusion indicate that the piezoelectric mechanism coming from ionic pairs applies equally well to the PZT ceramic. Co-doping Li+ and Al3+ into the A-site is a preferable approach for the piezoelectric property enhancement of ABO3 ferroelectric ceramics.

Semiconductor materials based UV photodetectors can be operated via photovoltaic effect by converting UV light into electric signals. Recent studies have been focused on how to fabricate excellent semiconductor materials based photodetectors through construction of heterojunctions, which may not be suitable for practical large-scale devices due to the high cost and sophisticated fabrication process. Here, by utilizing naturally existing temperature change of UV illumination and the pyroelectric effect of ferroelectric materials, a novel self-powered UV photodetector based on Pb(Zr,Ti)O 3 (PZT) material is presented through a simple fabricating process, which can be well utilized to detect 365 nm UV light by using light-induced temperature variation. Under a temperature change rate of 2.40 K s −1 , the voltage response and the corresponding responsivity can be enhanced by larger than 6600% as compared with that of individual UV light illumination. This study provides a feasible solution to realize self-powered UV light detection by utilizing light-induced pyroelectric effect in PZT.

Herein, the effect of the binder content in lead zirconate titanate (PZT) slurry has been systematically studied to improve the piezoelectric properties of PZT ceramics prepared via material extrusion 3D printing . For smooth printing, a slurry with a binder concentration ranging from 6 to 12 wt% was proposed. The porosity of the green body first decreased and then increased with an increase in the binder concentration, and the minimum porosity was obtained when the binder concentration reached 10 wt%. Samples with increased density were obtained after debinding and lead-rich atmosphere sintering. PZT piezoceramics fabricated using a binder content of 10 wt% exhibit the maximum relative density (96.9%), largest piezoelectric constant (342.6 pC/N) and dielectric constant (1621). Based on the above process, the wood pile structure and helical twentytetrahedral structural components were successfully fabricated using the material extrusion process. This research lays the foundation for the engineering application of 3D printing to fabricate high-performance piezoceramics with complex shapes.

PZT-8 ceramics exhibit outstanding performance in sensor applications owing to their superior piezoelectric properties. Nevertheless, conventional dense PZT-8 ceramics are subject to certain limitations, including high acoustic impedance and relatively low energy conversion efficiency, which restrict their broader application potential. Porous architectures offer a viable solution by enabling controlled porosity, thereby improving acoustic matching and enhancing energy harvesting efficiency. Although 3D printing presents a cost-effective method for fabricating complex ceramic geometries, ultraviolet (UV) light-based photopolymerization techniques have encountered challenges in processing PZT-8 ceramics due to their strong UV absorption characteristics. To address this limitation, this study introduces a novel strategy by incorporating non-absorbent polymethyl methacrylate (PMMA) into the formulation of high-performance porous PZT-8 piezoelectric ceramics tailored for digital light processing (DLP)-based 3D printing. Systematic investigations demonstrate that increasing PMMA content (5 wt% to 25 wt%) positively influences curing depth while simultaneously affecting microstructure and electrical properties. The experimental results show d 33 values ranging from 176 to 272 pC/N, k t values from 35.84% to 46.55%, Z values from 18.13 to 22.22 MRayls, FOM values from 8.92 to 10.55 × 10 -12 m 2 /N, and HFOM values from 3.47 to 4.40 × 10 -12 m 2 /N.

Piezoelectric PZT ceramics with high piezoelectric properties and good thermal stability are urgently desired concerning the practical application. New compositions of LiNbO 3 modified Pb(Ni 1/3 Nb 2/3 )O 3 PbZrO 3 PbTiO 3 ceramics have been prepared in this study. The effects of the introduction of the LiNbO 3 on the system were comprehensively investigated in terms of the phase structure, microstructure, electric properties, and thermal stability behavior of the ceramics. All compositions are located in the morphotropic phase boundary (MPB) region, and the ratio of the rhombohedral (R) phase increases obviously with the increase of LiNbO 3 concentration. With increasing the LiNbO 3 content, the piezoelectric properties were significantly enhanced. The sample added with 2% (in mole) LiNbO 3 shows excellent electric properties, including T m = 185 °C, ε r = 5,643, k p = 0.626, Q m = 51, d 33 = 902 pC/N. More importantly, no thermal depolarization behavior was observed in the temperature range of 25–100 °C. For PNN-PZT- x %LN ceramics, which is mainly attributed to the pinning effect resulted by the Li Pb ' − Nb Zr/Ti ∙ defect dipoles.

The transformation of environmentally benign waste energy into functional electricity holds profound implications for advancements in human progress. Herein, we detail the synthesis of tubular nanofibers featuring a hollow architecture through an innovative combination of sol-gel processing and electrospinning techniques , followed by surface modification with dopamine. These engineered PZT hollow nanotubes , upon integration into PVDF piezoelectric films, serve as potent reinforcing agents that amplify the piezoelectric active phase within the PVDF matrix. The introduction of these hollow PZT nanostructures alters the polarization electric field distribution, thereby augmenting the polarization dynamics of PVDF and significantly enhancing the piezoelectric performance of the resultant PVDF/PZT composite films . Our novel nano-generator exhibits an exceptional balance between a high piezoelectric coefficient , superior output characteristics, and commendable stability. Notably, the piezoelectric constant ( d 33 ) of Neat PVDF films experiences a substantial elevation from 9 pC N −1 to 20 pC N −1 , representing an impressive enhancement of approximately 122 %. Furthermore, the power density achieves a value of 0.54 μW cm −2 . This study introduces an effective approach to augment the productive output capability of composite nanogenerators, paving the way for sustainable energy harvesting technologies.

Polymer-based composites with high dielectric constant and suppressed dielectric loss were successfully fabricated by using PZT@Ag core-shell structured particles as fillers and PVDF as polymer matrix. The PZT@Ag core-shell structured particles were synthesized via conventional solid-state method. The results indicate that the fillers dispersed in the polymer matrix prominently enhance the dielectric constant while keeping the dielectric loss unchanged simultaneously. Composites with high dielectric constant result from the high dielectric constant of PZT itself, the superior interfacial polarization of PZT@Ag core-shell structure and the conductivity of Ag according to percolation theory, while the dielectric loss is suppressed due to the tunneling current decreasing among Ag particles and Coulomb blockade effect.

Piezoelectric nanogenerators (PENGs) that can harvest mechanical energy from ambient environment have broad prospects for multi-functional applications. Here, multi-layered piezoelectric composites with a porous structure based on highly oriented Pb(Zr 0.52 Ti 0.48 )O 3 /PVDF (PZT/PVDF) electrospinning fibers are prepared via a laminating method to construct high-performance PENGs. PZT particles as piezoelectric reinforcing phases are embedded in PVDF fibers and facilitate the formation of polar β phase in PVDF. The multi-layered, porous structure effectively promotes the overall polarization and surface bound charge density, resulting in a highly efficient electromechanical conversion. The PENG based on 10 wt% PZT/PVDF composite fibers with a 220 µm film thickness outputs an optimal voltage of 62.0 V and a power of 136.9 µW, which are 3.4 and 6.5 times those of 10 wt% PZT/PVDF casting film-based PENG, respectively. Importantly, the PENG shows a high sensitivity of 12.4 V·N −1 , presenting a significant advantage in comparison to PENGs with other porous structures. In addition, the composites show excellent flexibility with a Young’s modulus of 227.2 MPa and an elongation of 262.3%. This study shows a great potential application of piezoelectric fiber composites in flexible energy harvesting devices.

The textile industry encounters serious environmental challenges from wastewater with persistent organic pollutants, demanding sustainable solutions for remediation. Herein, we report a novel green synthesis of flexible BiOBr@PZT nanocomposite membranes via electrospinning and successive ionic layer adsorption and reaction (SILAR) for visible-light-driven photocatalytic degradation. The hierarchical structure integrates leaf-like BiOBr nanosheets with PAN/ZnO/TiO2(PZT) nanofibers, forming a Z-scheme heterojunction. This enhances the separation of photogenerated carriers while preserving mechanical integrity. SILAR-enabled low temperature deposition ensures eco-friendly fabrication by avoiding toxic precursors and cutting energy use. Optimized BiOBr@PZT-5 shows exceptional photocatalytic performance, achieving 97.6% tetracycline hydrochloride (TCH) degradation under visible light in 120 min. It also has strong tensile strength (4.29 MPa) and cycling stability. Mechanistic studies show efficient generation of O2−and OH radicals through synergistic light absorption, charge transfer, and turbulence-enhanced mass diffusion. The material’s flexibility allows reusable turbulent flow applications, overcoming rigid catalyst limitations. Aligning with green chemistry and UN SDGs, this work advances multifunctional photocatalytic systems for scalable, energy-efficient wastewater treatment, offering a paradigm that integrates environmental remediation with industrial adaptability.

Flexible piezoelectric energy harvesters (PEHs) have attracted extensive interest because of their ability to transform mechanical energy into electric power. Here, PEHs were fabricated using P(VDF-TrFE)-based piezoelectric composite films containing lead zirconate titanate (PZT) powder and –OH-functionalized graphene (HOG) nanosheets (HOG-P/P). Among all composites, a high open-circuit voltage ( V oc) of approximately 50 V p-p and a maximum power density of 1.4 μW/cm 2 were obtained from a HOG-P/P PEH with 0.10 wt% HOG nanosheets and 15 wt% PZT under bending–releasing mode. Moreover, the PEH exhibited a stable voltage output after 3000 bending–releasing cycles. In addition, the PEH harvested mechanical energy from human body movements and generated an output voltage and current of 60 V and 8 μA during the finger bending–releasing process, lighting up 30 commercial white LEDs. The enhanced piezoelectric performance can be attributed to the introduction of HOG nanosheets and PZT powder. This work provides an effective strategy for improving the output performance of P(VDF-TrFE)-based PEHs.
