污染治理是困扰世界的难题，在富集和降解过程中需要大量的能量。然而，一些污染物，例如废水中的有机物，可以提供能源供应，但却被浪费了。在这里，我们报告了一个能量收集原电池，通过使用Pt箔作为阳极和2D K +-插层MnO2作为阴极，它结合了染料降解废水和能量收集过程中的降解过程。由于原电池的电偶效应，该电池可加速降解速率，并指示降解进程。该电池具有稳定的开路电压（0.45 V），可降解多种有机物并产生能量。这种策略的放大和模仿为在其他放热反应中收集废能提供了新的机会。
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 MnO2as 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.
