Herein, a new strategy for micro/nanoparticles removal in water using a triboelectric nanogenerator (TENG) is demonstrated. Removal process based on electrophoretic force can extract particles from water by its zeta potential due to the electric fields generated by the TENG, in other words, higher performance TENG removes more particles. High-performance TENG based on a three-dimensional porous-pyramid polydimethylsiloxane shows a power output nearly three times higher than that of a flat film-based TENG. With the proposed TENG, the removal rate is 21.4%, which is 5.6 times higher than that for the flat TENG (3.8%). By measuring the coverage area of the particles attached to the electrode, it was found that the removal of particles was significantly affected by the output voltage and operation time of the TENG. A TENG-driven self-powered electrophoretic system that removes sub-micron nanoparticles of polystyrene, CdSe/CdZnS, ZnO, and SiO₂ is successfully demonstrated.

在此，展示了一种使用摩擦纳米发电机 (TENG) 去除水中微/纳米颗粒的新策略。由于 TENG 产生的电场，基于电泳力的去除过程可以通过其 zeta 电位从水中提取颗粒，换句话说，更高性能的 TENG 去除更多的颗粒。基于三维多孔金字塔聚二甲基硅氧烷的高性能 TENG 的功率输出几乎是基于平面薄膜的 TENG 的三倍。使用提议的 TENG，去除率为 21.4%，是平面 TENG（3.8%）的 5.6 倍。通过测量附着在电极上的颗粒的覆盖面积，发现颗粒的去除受TENG的输出电压和工作时间的显着影响。₂演示成功。
