Abstract：TraditionalFentoncatalysts have problemssuchasnarrowpHvaluerequirements，easymetalaggregation，and lowelectrontransfereficiencyTherefore，apreassmblyone-stepthermalcondensationsynergisticstrategy isproposedto prepare catalysts.Using amorphous Cu/CN40O with Cu-Ncoordination structure as coppersource （to suppress aggregation）， melamine as carbon nitride precursor，and CoCl2 ascobalt source，we synthesized Cu/Co-doped carbon nitride （Cu/CoCN） composite materials through template-freeself-assmblyto form pre-polymer.Characterizationrevealed thatthe material exhibits rod-like structure with triazine-based carbon nitride matrix，where Cu+/Cu2+ and Co2+/Co3+ ions are anchored to nitrogensitesviacoordination bonds，achievinguniform bimetallicdispersion.Performance tests demonstrated thatthe bimetallc material Cu/CoCN（1.5） achieved 95.6% degradation rate of 10 mg/L rhodamine B within 1h .The core innovation ofthis studyliesinleveragingthepre-coordinationcharacteristicsofCu-NinCu/CN4oOintermediatetoaddressbimetallic agregation at source，ensuringactive site exposure.Byconstructing synergistic Cu-N/Co-Ncoordination structures，the catalyticperformanceof thecatalyst was simultaneouslyenhanced，providing anovelparadigmforactivityregulation in bimetallic Fenton catalysts.
