| Popis: | Pollution treatment, a problem our world is being deeply puzzled by, has required large amounts of energy during enrichment and degradation. However, some pollutants, for instance organics in wastewater, could offer an energy supply but instead are wasted. Here we report an energy harvesting galvanic cell, built by using a Pt foil as an anode and 2D K+-intercalated MnO2 as a cathode, which combines both dye degradation in wastewater and energy harvesting during the degradation process. Owing to the galvanic effect, this cell could accelerate the degradation rate and indicate the progress of degradation. Different kinds of organics could be degraded and produce energy in this cell with a stable open-circuit voltage (0.45 V). Magnification and imitation of this strategy offer a new chance to harvest waste energy in other exothermic reactions. |
