The built-in electric field can be generated in the piezoelectric materials under mechanical stress. resulting effect is beneficial to charge separation photocatalysis. Meanwhile, stress usually gives rise accelerated mass transfer and enhanced catalytic activity. Unfortunately, it remains a challenge differentiate contribution of these two factors performance. Herein, for first time, isostructural metal-organic frameworks (MOFs), i.e., UiO-66-NH2 (Zr) (Hf), are adopted piezo-photocatalysis. Both MOFs, featuring same structures except diverse Zr/Hf-oxo clusters, possess distinctly different properties. Strikingly, (Hf) exhibits ≈2.2 times activity compared with that simultaneous light ultrasonic irradiation, though both MOFs display similar photocatalytic H2 production without irradiation. Given their pore features behaviors, difference unambiguously assignable effect. As result, contributions piezo-photocatalysis clearly distinguished owing stronger property (Hf).

Abstract Emerging piezocatalysts have demonstrated their remarkable application potential in diverse medical fields. In addition to ultrahigh catalytic activities, inherent and unique charge‐carrier‐releasing properties can be used initiate various redox reactions, displaying bright prospects for future applications. Triggered by mechanical energy, piezocatalytic materials release electrons/holes, catalyze reactions of substrates, or intervene biological processes promote the production effector molecules purposes, such as decontamination, sterilization, therapy. Such a piezocatalysis is termed medicine (PCM) herein. To pioneer novel technologies, especially therapeutic modalities, this review provides an overview state‐of‐the‐art research progress medicine. First, principle preparation methodologies piezoelectric are introduced. Then, comprehensive summary applications tumor treatment, antisepsis, organic degradation, tissue repair regeneration, biosensing provided. Finally, main challenges perspectives discussed proposed, expecting fuel development emerging scientific discipline.

In this work, Ag/Bi5O7I nanocomposite was prepared and firstly applied in piezo/photocatalytic reduction of N2 to NH3 methyl orange (MO) degradation. Bi5O7I synthesized via a hydrothermal-calcination method shows nanorods morphology. Ag nanoparticles (NPs) were photo deposited on the as electron trappers improve spatial separation charge carriers, which confirmed XPS, TEM, electronic chemical analyses. The catalytic test indicates that presents piezoelectric-like behavior, while loading NPs can strengthen character. Under ultrasonic vibration, optimal high efficiency MO degradation rate is determined be 0.033 min−1, 4.7 folds faster than Bi5O7I. also performance piezocatalytic fixation. generation reaches 65.4 μmol L−1 g−1 h−1 with water hole scavenger. addition methanol hasten piezoelectric reaction. Interestingly, when vibration light irradiation simultaneously act catalyst, higher observed. However, due weak adhesion NPs, some would fall off from surface under long-term greatly reduce performance. This result strong binding force required preparing composite catalyst. current work provides new insights for development highly efficient catalysts use multiple energies.

Mechanochemistry has been studied for some time, but research on the reactivity of charges exchanged by contact-electrification (CE) during mechanical stimulation remains scarce. Here, we demonstrate that electrons transferred CE between pristine dielectric powders and water can be utilized to directly catalyze reactions without use conventional catalysts. Specifically, frequent at Fluorinated Ethylene Propylene (FEP) - interface induces electron-exchanges, thus forming reactive oxygen species degradation an aqueous methyl orange solution. Contact-electro-catalysis, conjunction CE, mechanochemistry catalysis, proposed as a general mechanism, which demonstrated effective various materials, such Teflon, Nylon-6,6 rubber. This original catalytic principle not only expands range also enables us envisage processes through mechano-induced contact-electrification.

Solar-driven overall water splitting is an ideal way to generate renewable energy while still challenging. For the first time, this work combined covalent organic frameworks (COFs) and piezoelectric material by linkages form Z-scheme core@shell heterostructure for splitting. Benefiting from synergistic effect between polarized electric field photo-generated charges, as well precise adjustment of shell thickness, carrier separation utilization efficiency greatly improved.
