Rotation-mode liquid-solid triboelectric nanogenerator for efficient contact-electro-catalysis and adsorption

Contact-electro-catalysis has been shown to be a new method for catalytic degradation of pollutants. However, the catalytic efficiency of contact-electro-catalysis (CEC) realized by ultrasonic method still has great potential for improvement. Here, we propose a wind-driven, Al@Al2O3 and PTFE combined rotational mode liquid-solid triboelectric nanogenerator (TENG) contact-electro-catalytic and adsorbable device. The contact electrification of the liquid-solid interface during mechanical rotation makes the treatment efficiency of organic pollutants much higher than other advanced oxidation processes. Taking crystal violet (CV) as the target pollutant, when the linear speed of the rotator is 1.41 m s-1, the k values for low-concentration and high-concentration crystal violet are 2.24 min-1 and 0.26 min-1, respectively. This is a huge advance in the field of catalysis. In addition, the device can also monitor the treatment progress of organic pollutants in real time.
