Nitrophenols (NPh) are hazardous pollutants with potentially harmful health effects. Conducting polymers appear as attractive candidates to detect and degrade these compounds due to their electrocatalytic activity. However, using electrocatalytic processes to degrade the micropollutants and harnessing the energy used in this process is a new standpoint. To obtain this cooperative effect, we explored the multifunctionality of PEDOT nanotubes in energy storage and electrocatalysis of NPh. The energy involved in degradation was harnessed in a high-performance supercapacitor, by increasing the specific capacitance in almost 50% in some configurations. The presence of NPh during the charge and discharge cycles also increased the stability and durability of the PEDOT nanotubes by forming poly(aminophenols). The extension of NPh degradation was evaluated by UV–vis spectroscopy and the modified electrodes were characterized by electrochemical, vibrational spectroscopic and scanning electron microscopy techniques. By this way, this contribution presents an interesting perspective gathering the degradation of micropollutants and the energy storage devices, which are certainly two of the biggest concerns of the scientific community nowadays.

硝基苯酚（NPh）是有害污染物，对健康有潜在危害。导电聚合物由于其电催化活性而成为检测和降解这些化合物的诱人候选物。然而，使用电催化方法降解微污染物并利用该方法中使用的能量是一个新的观点。为了获得这种协同作用，我们探索了PEDOT纳米管在NPh的能量存储和电催化中的多功能性。在某些配置中，通过将比电容提高近50％，可以在高性能超级电容器中利用退化所涉及的能量。通过形成聚（氨基酚），在充电和放电周期中存在NPh也增加了PEDOT纳米管的稳定性和耐用性。NPh降解的扩展通过紫外可见光谱进行了评估，修饰的电极通过电化学，振动光谱和扫描电子显微镜技术进行了表征。通过这种方式，这一贡献提出了一个有趣的观点，收集了微污染物和能量存储设备的降解，这无疑是当今科学界关注的两个最大问题。
