Herein, we construct a unique hybrid system by combining self-powered triboelectric nanogenerator (TENG) with carbon dots-TiO<sub>2</sub> sheets doped three-dimensional graphene oxide photocatalyst (3DGA@CDs-TNs), which can significantly enhance the degradation efficiency of brilliant green (BG) and direct blue 5B (DB) owing to the powerful interaction of TENG and 3DGA@CDs-TNs photocatalyst. The power output of TENG can be applied for wastewater purification directly, which exhibits a self-powered electrocatalytic technology. Furthermore, the results also verify that TENG can replace conventional electric catalyst to remove pollutants effectively from wastewater without any consumption. Subsequently, the unstable fragments and the plausible removal pathways of the two pollutants are proposed. Our work sheds light on the development of efficient and sustainable TENG/photocatalyst system, opening up new opportunities and possibilities for comprehensive utilization of random energy.</p> <p>Highlights:</p> <p>1 Triboelectric nanogenerator (TENG)/carbon dots-TNs supported over three-dimensional graphene aerogel (3DGA@CDs-TNs) system was constructed.<br>2 TENG and 3DGA@CDs-TNs present excellent degradation activity toward brilliant green (88.26%, 40 min) and direct blue 5B (89.6%, 90 min).<br>3 The coupling interaction of photocatalysis and TENG leads to an enhanced removal ability.<br>4 The degradation pathways for brilliant green and direct blue 5B are proposed.</p>}, journal={Nano-Micro Letters}, author={Shen, Shen and Fu, Jiajia and Yi, Jia and Ma, Liyun and Sheng, Feifan and Li, Chengyu and Wang, Tingting and Ning, Chuan and Wang, Hongbo and Dong, Kai and Wang, Zhong Lin}, year={2021}, month={Sep.}, pages={194} }
