dc.description.abstract | In this study, a facile approach has been successfully applied to synthesize a W-doped Fe2O3/MoS2 core-shell electrode with unique nanostructure modifications for photoelectrochemical performance. A two-dimensional (2D) structure of molybdenum disulfide (MoS2) and tungsten (W)-doped hematite (W:alpha-Fe2O3) overcomes the drawbacks of the a-Fe2O3 and MoS2 semiconductor through simple and facile processes to improve the photoelectrochemical (PEC) performance. The highest photocurrent density of the 0.5W:alpha-Fe2O3/MoS2 photoanode is 1.83 mA.cm(-2) at 1.23 V vs reversible hydrogen electrode (RHE) under 100 mW.cm(2) illumination, which is higher than those of 0.5W:alpha-Fe2O3 and pure alpha-Fe2O3 electrodes. The overall water splitting was evaluated by measuring the H-2 and O-2 evolution, which after 2 h of irradiation for 0.5W:alpha-Fe2O3/MoS2 was determined to be 49 and 23.8 mu mol.cm(-2), respectively. The optimized combination of the heterojunction and metal doping on pure alpha-Fe2O3 (0.5W:alpha-Fe2O3/MoS2 photoanode) showed an incident photon-to-electron conversion efficiency (IPCE) of 37% and an applied bias photon-to-current efficiency (ABPE) of 26%, which are around 5.2 and 13 times higher than those of 0.5W:alpha-Fe2O3, respectively. Moreover, the facile fabrication strategy can be easily extended to design other oxide/carbon-sulfide/oxide core-shell materials for extensive applications. | - |
