Built-in electric field activates endogenous redox couple for self-sustained Fenton-like reaction (opens in new tab)

Heterogeneous catalyst systems hold significant potential for advanced water treatment, yet achieving sustainable catalytic processes capable of continuously generating reactive species remains a substantial challenge. In this work, we develop an integrated oxidation-reduction system that synergistically couples peracetic acid (PAA) with H2O2 under the guidance of an interfacial built-in electric field (BEF). Through a programmable self-assembly approach, a porous nitrogen-doped carbon (NC) l...
