摘要

压电光催化是一种很有前途的混合高级氧化工艺，利用光照射和机械振动来去除废水中的抗性有机污染物。该工艺通过耦合压电和光催化活性，提供了光催化效率的协同增强，解决了传统光催化的局限性，包括在没有照明的情况下快速的电子-空穴对重组和失活。我们简要回顾了用于废水处理的钛基压电半导体的最新进展，重点介绍了2020年至2025年的研究进展。本文综述了基于材料的研究，主要分为两大类：集成ti基压电光催化剂和混合压电材料-掺杂TiO2光催化剂。我们批判性地讨论了压电电位和相应的内部电场对光致电荷分离和活性氧生成的影响。探讨了评估压电和光催化性能的方法。本文综述了压电光催化的潜在应用和面临的挑战，并为废水处理中高级氧化工艺的未来发展提供了见解。

Recent progress on Ti-based piezo-photocatalysts for wastewater treatment

Piezo-photocatalysis has emerged as a promising hybrid advanced oxidation process to eliminate resistant organic pollutants in wastewater via harnessing light irradiation and mechanical vibration. This process offers a synergistic enhancement of photocatalytic efficiency by coupling piezo-electricity with photocatalytic activity, addressing limitations of conventional photocatalysis, including rapid electron-hole pairs recombination and deactivation in the absence of illumination. We concisely review recent advancements in Ti-based piezo-electric semiconductors for wastewater treatment, focusing on research from 2020 to 2025. The studies included in this review are based on materials categorized into two main groups: integrated Ti-based piezo-photocatalysts and hybrid piezo-electric materials-incorporated TiO₂ photocatalysts. We critically discuss the impact of piezo-potential and corresponding internal electric fields on photoinduced charge separation and reactive oxygen species generation. Methodologies for assessing the piezo-electric and photocatalytic properties are explored. This review highlights piezo-photocatalysis’s potential applications and challenges, offering insights into future developments in advanced oxidation processes for wastewater treatment.

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
