Photoelectrochemical Oxygen and Hydrogen Evolution with Various Electron Transfer Mediators |
| 초록 |
WO3 and Fe2O3 are well-known Photocatalysts for hydrogen and oxygen evolution under visible light irradiation. Generally the ability of Ag+ for electron acceptor is well known but its reaction is irreversible because the Ag+ get one electron from conduction band of WO3 and precipitated as a form of Ag metal. On the other hand, Fe3+ and IO3- make redox with Fe2+ and I- comparatively. Although Photocatalytic activity of WO3 in oxygen evolution experiments with the solution of Ag+ was best and next was Fe3+ solution, the reoxidations of Ag metal and Fe2+ which are reduced by the electron of conduction band of WO3 did not occur in hydrogen evolution experiment with hydrogen producing photocatalysts. The redox iodide/iodate was worked between WO3 as oxygen producing photocatalysts and AgGaS2 as hydrogen producing photocatalyst. |
