Abstract
AbstractElectrochemical degradation is a commonly used strategy to remove organic contaminations in water. However, in some remote areas where electricity is insufficient, electrochemical degradation may become ineffective due to the absence of a power supply. Here, a unique self‐powered electrochemical system (SPES) is proposed to accomplish the power‐free degradation of tetracyclines (TCs) and organic dyes in water with the assistance of flexible magnetoelectric flag generators (MFGs). These MFGs convert wind energy into electricity. Under a wind speed of 6.3 m s−1, a 22 × 30 cm2 MFG yields a peak open‐circuit voltage of 3.5 V and an ultra‐high peak short‐circuit current of ≈13 mA. A suchlike MFG charges large capacitors of 5 F to 1 V in 184 min. Powered by a series of MFGs, 5 ppm of tetracycline hydrochloride (TCH) or organic dyes in water are totally degraded with SPES in only 10 min. Moreover, the MFG is fully foldable and portable, which is well‐suited for the migrating feature of the nomadic people in remote areas. The study opens up a new solution to the persistent problem of TCs contamination in natural waters in some remote regions where electricity is lacking.
