【 摘 要 】

tsTriboelectric nanogenerator (TENG)/carbon dots-TNs supported over three-dimensional graphene aerogel (3DGA@CDs-TNs) system was constructed.TENG and 3DGA@CDs-TNs present excellent degradation activity toward brilliant green (88.26%, 40 min) and direct blue 5B (89.6%, 90 min).The coupling interaction of photocatalysis and TENG leads to an enhanced removal ability.The degradation pathways for brilliant green and direct blue 5B are proposed.
