| Outline of Final Research Achievements |
A facile and efficient process for the large-scale synthesis of Ag3PO4 cube structures thin films exposed with {100} facets was prepared by the direct oxidation of Ag foils with H2O2 at room temperature. The photoelectrochemical performance of the thin film electrodes for water splitting that took place in Na2HPO4 aqueous solution was strongly dependent on the polyvinylpyrrolidone concentration used for the direct oxidation process. The photo-anode exhibited the bandgap of 2.2 eV and high photocatalytic efficiency, as well as an incident photon-to-current conversion efficiency (IPCE) of 57%, for the photoelectrochemical oxidation of water.
