dc.description.abstract | We report great enhancement in photoelectrochemical water splitting efficiency of hematite assisted by fast and easy transfer of electrons/holes via a 3D-nanoporous gold (3D-NG) electrode. 3D-nanostructured alpha-Fe2O3/NG electrodes were fabricated in three subsequent procedures, de-alloying Au/Ag to produce a conductive 3D-NG electrode, decorating nanocrystalline beta-FeOOH onto the nanopores of 3D-NG via a hydrothermal method, and converting beta-FeOOH into alpha-Fe2O3. alpha-Fe2O3/3D-NG exhibits a maximum photocurrent density of 1.6 mA cm(-2) at 1.5 V vs. RHE under AM 1.5 G simulated sunlight illumination via a photocatalytic hydrogen generation reaction, which is 2 times greater than that of the unmodified alpha-Fe2O3 photoanode. Incident photon-to-electron conversion efficiency (IPCE) and electrochemical impedance spectroscopy (EIS) data confirm that alpha-Fe2O3/3D-NG suppresses electron-hole recombination. The excellent performance of nanostructured hematites on 3D-nanoporous metal electrodes makes them promising candidates as electrodes with maximum efficiency in water splitting. | - |
