Solar interfacial evaporation (SIE) process offers an effective and sustainable approach for alleviating freshwater shortage, but the simultaneous evaporation of volatile organic compound (VOC) limits the application of this technique. Herein, a novel electro-Fenton assisted SIE (EF/SIE) was proposed for the first time to co-enhance steam generation and VOC removal based on an evaporator composed of graphite felt decorated with Fe/N-doped porous carbon (FeNCx/GF). This dual functional evaporator integrating photothermal and electrocatalytic technology achieved a "self-sufficient" degradation process, in which FeNCx acted as the heterogeneous electrocatalyst to in-situ produce H
