Facile Routes to Produce Hematite Film for Hydrogen Generation from Photoelectro-Chemical Water Splitting

In this chapter, we brief review a recent progress in chemical synthesis used to prepare very promise material to be applied as photoanode in a PEC cell. We discuss the important parameters such as; the interface solid/liquid showing the different challenge that needs to be addressed for obtains higher semiconductor photoanode performance. In addition, we discuss the impact of a variety of morphology applied in a PEC cell to split water and generate hydrogen and oxygen molecular. Finally, we have pointed out the progress of molecular oxygen evolution mechanism from water oxidation under solar light irradiation.
