Energy Challenge

Solar-driven water splitting technology is considered to be a promising solution for the global energy challenge as it is capable of generating clean chemical fuel from solar energy. Various strategies and catalytic materials have been explored in order to improve the efficiency of the water splitting reaction. Although significant progress has been made, there are many intriguing fundamental phenomena that need to be understood. Herein, we review recent experimental efforts to demonstrate enhancement strategies for efficient solar water splitting, especially for the light absorption, charge carrier separation, and water oxidation kinetics. We also focus on the state of the art of photoelectrochemical (PEC) device designs such as application of facet engineering and the development of a ferroelectric-coupled PEC device. Based on these experimental achievements, future challenges, and directions in solar water splitting technology will be discussed.

In this study, we report the successful preparation of hematite nanostructures coated with thin titania layer for potential solar water splitting applications. The prepared samples were studied systematically by a range of analysis techniques. We showed that resulting hybrid hematite-titania nanosystem exhibited improved photoelectrochemical activity for solar water splitting compared to the bare hematite only. We also showed that this enhancement was achieved through an improvement in light harvesting and better charge carrier separation. Thus, these findings may open new perspectives for the development of photoelectrodes used in photoelectrochemical water splitting applications.
