Self-powered cleaning of air pollution by wind driven triboelectric nanogenerator

Self-powered air cleaning system focusing on sulfur dioxide (SO2) and dust removal is developed with the use of rotating triboelectric nanogenerator (R-TENG). A high power density of 3.4 mA and a high voltage of 300 V generated from natural wind with the use of R-TENG are utilized to oxidize the SO2 and adsorb the flying dust in the air.
