In recent years, air pollution has detrimentally affected human health. Particulate matter (PMx) is a primary component of air pollution, and significant research effort has been devoted to developing feasible technologies for its removal. In this study, a radial piston triboelectric nanogenerator (RP-TENG) enhanced cellulose fiber air filter (CFAF) was developed to remove PMx from outdoor ambient air. This self-powered PMx removal system can not only convert rotating mechanical energy into electrical energy, but it can automatically remove polluted air from the outdoor environment. After charging, the removal efficiency of the CFAF was 83.78% for PM2.5 and 86.82% for PM10, which were 1.21 times and 1.27 times greater than those of the uncharged system, respectively. The self-powered PMx removal system can be installed on an object with rotating mechanical energy, such as the rotating shaft of a shared bicycle, and the wasted rotating mechanical energy would be used to fully purify the outdoor environment. Furthermore, this system is environmentally friendly due to its low level of carbon emissions. This work has numerous potential applications as it provides a new and sustainable strategy for applying self-powered, TENG-enhanced air filters for the removal of PMx from outdoor air.

径向活塞式摩擦电纳米发电机增强型纤维素纤维空气过滤器,用于去除自供电的颗粒物

近年来,空气污染已严重危害人类健康。颗粒物(PMx)是空气污染的主要组成部分,并且已经进行了大量的研究工作以开发可行的技术来去除它。在这项研究中,开发了一种径向活塞式摩擦电纳米发电机(RP-TENG)增强型纤维素纤维空气滤清器(CFAF),以去除室外环境空气中的PMx。这种自供电的PMx去除系统不仅可以将旋转的机械能转换为电能,还可以自动去除室外环境中的污染空气。充电后,CFAF的去除效率对于PM 2.5和PM 10分别为83.78%和86.82%,分别是未充电系统的1.21倍和1.27倍。自供电的PMx去除系统可以安装在具有旋转机械能的物体上,例如共享自行车的旋转轴,而浪费的旋转机械能将用于充分净化室外环境。此外,由于该系统的碳排放量低,因此对环境无害。这项工作具有许多潜在的应用,因为它提供了一种新的,可持续的策略,可以应用自供电,TENG增强的空气过滤器去除室外空气中的PMx。
