In a dual-chamber photocatalytic fuel cell device,polyvinyl alcohol degradation and H2 evolution were concurrently achieved.The setup involved commer-cial P25 as the photoanode and Ag@Fe2O3 nanoparticles as the cathode.Additionally,the feasibility of a Fenton-like reaction in the cathode,utilizing Fe2+ions and pumped O2,was demonstrated.Different cathode materials,polyvi-nyl alcohol types,and pH values'effects were assessed on device performance.Quenching tests highlighted photoin-duced holes(h+)and OH-radicals as pivotal contributions to polyvinyl alcohol degradation.Long-term stability of the device was established through cycling experiments.
