压电催化是一种新兴技术，有望通过压电效应将无处不在的机械能转化为电化学能。然而，自然环境中的机械能（如风能、水流能、噪声等）通常具有微小、分散、频率低、功率小的特点。因此，对这些微小机械能的高响应对于实现高压电催化性能至关重要。与纳米粒子或一维压电材料相比，二维压电材料具有高柔韧性、易变形、比表面积大、活性位点丰富等特点，在未来的实际应用中显示出更大的前景。在这篇综述中，提供了二维压电材料及其在压电催化中的应用的最新研究进展。首先，提供了二维压电材料的详细描述。然后对压电催化技术进行了全面的总结，并研究了二维压电材料在环境修复、小分子催化和生物医学等各个领域的压电催化应用。最后，讨论了二维压电材料及其在压电催化中的应用面临的主要挑战和前景。预计该综述可以推动二维压电材料在压电催化中的实际应用。

An Emerging Family of Piezocatalysts: 2D Piezoelectric Materials

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