A new method for the fabrication of a bilayer WO3/Fe2O3 photoelectrode for enhanced photoelectrochemical performance
Source abstract
Abstract
Abstract A bilayer WO 3 /Fe 2 O 3 heterojunction photoelectrode was prepared with a new approach for photoelectrochemical reactions. WO 3 was deposited onto an FTO conductive glass substrate via electrodeposition, followed by the deposition of an ultrathin Fe 2 O 3 layer using the chemical bath deposition method. The presence of Fe 2 O 3 layer improved the light absorption of WO 3 /Fe 2 O 3 toward visible light region (red-shift). The addition of a thin layer of Fe 2 O 3 on WO 3 resulted in higher photocatalytic performance (two-fold improvement) compared to that of pristine WO 3 . In addition, the WO 3 /Fe 2 O 3 photoelectrode also showed a positive photoresponse for methanol degradation. The photocurrent generation of the bilayer photoelectrode improved 1.6-fold with the addition of methanol as a sacrificial donor.
