Abstract： Complete mineralization persistent organic pollutantsin wastewater remainsa midable challenge. Here， we report the rational design a ZIF-8-derived ZnO/polyaniline （PANl） S-scheme heterojunction synthesized viainsitu oxidative polymerization.characterizationsconfirm the Sscheme charge transfer mechanism within the ZnO/PANl heterojunction. The optimized compositeachievescompletephenolmineralizationwithin 60min while concurrently generating H2O2 at a rate 0.75mmol⋅L-1⋅h-1 under simulated solar iradiation.Mechanistic studies verify thatthe S-scheme heterojunctionretains strong redox potentials，driving the mation reactive oxygen species H2O2 production phenol degradation.This work establishesauniversal design paradigm MOF-derivedinorganic/organic Sscheme heterojunctions，effectively coupling solar-driven energy conversion with environmental remediation.
