| Abstract |
The ultrasonic-assisted synthesis method provides a fast, simple, and large scale route for synthesizing desired materials under ambient conditions. Here, the facile preparation of ZnO-ZnS composite on a fluorine-doped tin oxide (FTO) substrate. The composite was synthesized by sequential nanoscale reactions involving the preparation of ZnO and conversion of the ZnO surface into a ZnS shell on the FTO substrate, using an in situ sonochemical method. The ZnO-ZnS composite showed improved photocurrents compared to ZnO for the water oxidation reaction. During the water oxidation reaction, the ZnS shell passivates the surface-degects of the ZnO, which results in enhanced charge separation in the ZnO nanorods and higher performance.
