A facile way to synthesize Er2O3@ZnO core-shell nanorods for photoelectrochemical water splitting

• Er2O3@ZnO core-shell nanorods were successfully fabricated by an electrochemical process.
• The as-prepared composites exhibited improved photocurrent under the light irradiation.
• The results indicate that the composites hold great promise for PEC water splitting.

In this study, we demonstrated large-scale Er2O3@ZnO core-shell nanorods with great photoelectrochemical water splitting ability, which were successfully fabricated by a simple and facile electrodeposition. These Er2O3@ZnO core-shell nanorods exhibited improved photocurrent under the light irradiation, which can be attributed to the enhanced donor density by the covered Er2O3.

In this paper, we reported a facile method to prepare Er2O3@ZnO core-shell composites and examined their applications as photo-anodes in photoelectrochemical water splitting. The as-fabricated composites exhibited improved photocurrent under the light irradiation, which can be attributed to the enhanced donor density by the covered Er2O3.Figure optionsDownload as PowerPoint slide
