Oil spills represent a global concern with devastating consequences, impacting human health, marine ecosystems, and economies worldwide. Piezoelectric materials-substances that generate electricity in response to mechanical stress (e.g., waves, tides, or fluid dynamics)-offer unique advantages for addressing coastal oil spills. In this perspective, we explore the opportunities and challenges of applying piezoelectric materials in oil spill countermeasures. We first introduce multiple advantages of piezoelectric materials and piezocatalysis over conventional catalysis processes. From an energy-saving standpoint, we rationalize the necessity of deploying piezoelectric materials as a promising solution for oil spill mitigation, emphasizing their ability to harness renewable ocean energy. Through an examination of previous research, we summarize recent advancements in piezoelectric materials in surface washing, membrane separation, and hydrogel coating. By compiling numerous research findings, we identify critical bottleneck challenges in advancing piezoelectric material design and performance-such as saltwater-induced charge neutralization, structure optimization, and material durability-and propose corresponding solutions to enhance their practical utility. We hope this perspective provides valuable insights for developing cutting-edge piezoelectric materials tailored to effective, sustainable oil spill response strategies.
石油泄漏是一个全球性问题，会带来毁灭性后果，影响全球人类健康、海洋生态系统和经济。压电材料——即能响应机械应力（如波浪、潮汐或流体动力学）产生电能的物质——在应对沿海石油泄漏方面具有独特优势。从这一角度出发，我们探讨了应用压电材料应对石油泄漏的机遇与挑战。我们首先介绍了压电材料和压电催化相对于传统催化过程的多重优势。从节能的角度来看，我们阐述了部署压电材料作为减轻石油泄漏的一种有前景的解决方案的必要性，强调了它们利用可再生海洋能源的能力。通过审视以往的研究，我们总结了压电材料在表面清洗、膜分离和水凝胶涂层方面的最新进展。通过汇总大量研究结果，我们确定了推进压电材料设计和性能方面的关键瓶颈挑战——如盐水引起的电荷中和、结构优化和材料耐久性——并提出了相应的解决方案以提高其实际效用。我们希望这一观点能为开发适用于有效、可持续的石油泄漏应对策略的前沿压电材料提供有价值的见解。
