An Emerging Family of Piezocatalysts: 2D Piezoelectric Materials

Small, Год журнала: 2023, Номер 19(44)

Опубликована: Июнь 29, 2023

Abstract Piezocatalysis is an emerging technique that holds great promise for the conversion of ubiquitous mechanical energy into electrochemical through piezoelectric effect. However, energies in natural environment (such as wind energy, water flow and noise) are typically tiny, scattered, featured with low frequency power. Therefore, a high response to these tiny critical achieving piezocatalytic performance. In comparison nanoparticles or 1D materials, 2D materials possess characteristics such flexibility, easy deformation, large surface area, rich active sites, showing more future practical applications. this review, state‐of‐the‐art research progresses on their applications piezocatalysis provided. First, detailed description offered. Then comprehensive summary presented examines various fields, including environmental remediation, small‐molecule catalysis, biomedicine. Finally, main challenges prospects discussed. It expected review can fuel application piezocatalysis.

SnFe ₂O ₄/ZnIn ₂S ₄/PVDF piezophotocatalyst with improved photocatalytic hydrogen production by synergetic effects of heterojunction and piezoelectricity

Journal of Advanced Ceramics, Год журнала: 2023, Номер 12(9), С. 1685 - 1700

The polarized electric field inside piezoelectric materials has been proved to be promising technique boost the photogenerated charge separation. Herein, a novel flexible SnFe₂O₄/ZnIn₂S₄/PVDF (P-SZ) film piezophotocatalyst was successfully synthesized by combining poly vinylidene fluoride (PVDF), an organic material, with SnFe₂O₄/ZnIn₂S₄ (SFO/ZIS) type II heterojunction photocatalyst. hydrogen evolution rate of SFO/ZIS SFO content 5% is about 846.79 μmol h^-1 g^-1, which 3.6 times higher than that pristine ZIS. Further, after being combined PVDF, optimum P-SZ 1652.7 g^-1 in presence ultrasound, exceeds 5%SFO/ZIS approximately factor 2.0. Based on experimental results, mechanism improved photocatalytic performance proposed basis PVDF and formed between ZIS, effectively boosted separation photoinduced charges. This work provides efficient strategy for multi-path collection utilization natural solar vibrational energy enhance photoactivity.

Highly Efficient Fe^III‐initiated Self‐cycled Fenton System in Piezo‐catalytic Process for Organic Pollutants Degradation

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(32)

Опубликована: Июнь 15, 2023

Piezo-catalytic self-Fenton (PSF) system has been emerging as a promising technique for wastewater treatment, while the competing O2 reductive hydrogen peroxide (H2 ) production and FeIII reduction seriously limited reaction kinetics. Here, we develop two-electron water oxidative H2 (WOR-H2 coupled with over /BiOIO3 piezo-catalyst highly efficient PSF. It is found that presence of can simultaneously initiate WOR-H2 to FeII , thereby enabling rapid kinetics towards subsequent Fenton /FeII . The initiating PSF offers exceptional self-recyclable degradation pollutants rate constant sulfamethoxazole (SMZ) 3.5 times classic -PSF system. This study new perspective constructing systems shatters preconceived notion in reaction.
