Among the many environmental problems affecting human health and safety, the greatest threat caused by air and water pollutions affects millions of people globally. H2O2 is a clean oxidant for production of hydroxyl radicals (OH•) that decomposes nearly all the organic pollutants. However, the exiting Electro-Fenton (EF) strategies for producing H2O2 are still far unsatisfactory due to its intermittent production, negative decomposition, also the wide use of pure O2 or/and proton exchange membrane. Here, we report a wood-derived solid ionic conductor (WSIC) to propose a solid EF strategy that makes the continuous cathodic production of giant H2O2 only using ubiquitous air and water in nature. The activation of H2O2 by FeOCl generates OH• that continuously degrades either aqueous (99.9%, Rhodamine B), or mineralizes gaseous toluene into CO2 and H2O at room temperature. Our findings provide a fundamental step to develop next-generation of advanced oxidation processes with sustainability and cost-effectivity.
