Abstract:In a dual-chamber photocatalytic fuel cell device, polyvinyl alcohol degradation and H-2 evolution were concurrently achieved. The setup involved commercial 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 O-2, was demonstrated. Different cathode materials, polyvinyl alcohol types, and pH values' effects were assessed on device performance. Quenching tests highlighted photoinduced holes (h( )) and OH<middle dot> radicals as pivotal contributions to polyvinyl alcohol degradation. Long-term stability of the device was established through cycling experiments.
