Environmental and human health is severely threatened by wastewater and air pollution, which contain a broad spectrum of organic and inorganic pollutants. Organic contaminants include dyes, volatile organic compounds (VOCs), medical waste, antibiotics, pesticides, and chemical warfare agents. Inorganic gases such as CO, SO, and NO are commonly found in polluted water and air. Traditional methods for pollutant removal, such as oxidation, physicochemical techniques, biotreatment, and enzymatic decomposition, often prove to be inefficient, costly, or energy-intensive. Contemporary solutions like nanofiber-based filters, activated carbon, and plant biomass also face challenges such as generating secondary contaminants and being time-consuming. In this context, triboelectric nanogenerators (TENGs) are emerging as promising alternatives. These devices harvest ambient mechanical energy and convert it to electrical energy, enabling the self-powered degradation of chemical pollutants. This Review summarizes recent progress and challenges in using TENGs as self-powered electrochemical systems (SPECs) for pollutant degradation via photocatalysis or electrocatalysis. The working principles of TENGs are discussed, focusing on their structural flexibility, operational modes, and ability to capture energy from low-frequency mechanical stimuli. The Review concludes with perspectives and suggestions for future research in this field, hoping to inspire further interest and innovation in developing TENG-based SPECs, which represent sustainable and eco-friendly solutions for pollutant treatment.
废水和空气污染严重威胁着环境与人类健康，这些污染中含有各种各样的有机和无机污染物。有机污染物包括染料、挥发性有机化合物（VOCs）、医疗废物、抗生素、农药和化学战剂。诸如一氧化碳、二氧化硫和一氧化氮等无机气体在受污染的水和空气中很常见。传统的污染物去除方法，如氧化、物理化学技术、生物处理和酶分解，往往效率低下、成本高昂或能源密集。基于纳米纤维的过滤器、活性炭和植物生物质等现代解决方案也面临着产生二次污染物和耗时等挑战。在这种背景下，摩擦纳米发电机（TENGs）正成为有前途的替代方案。这些装置收集环境机械能并将其转化为电能，从而实现化学污染物的自供电降解。本综述总结了将TENGs用作自供电电化学系统（SPEC）通过光催化或电催化降解污染物的最新进展和挑战。讨论了TENGs的工作原理，重点关注其结构灵活性、操作模式以及从低频机械刺激中捕获能量的能力。综述最后对该领域未来的研究提出了展望和建议，希望能激发人们对开发基于TENG的SPEC的进一步兴趣和创新，这代表了污染物处理的可持续和环保解决方案。
