Photoelectrochemical water splitting based on nano-structure hematite is investigated for hydrogen generation from solar and water energy.Herein,a hollow nanorod hematite(HNR-α-Fe2O3)has been fabricated by a modified hydrothermal method and heat treatment.The SEM images indicate that the HNR-α-Fe2O3 has obviously nanorod morphology with pores,which made a rougher surface of α-Fe2O3.
