AbstractWe reported a facile adjusted method for the synthesis of high surface area nanorod hematite film as a photoanode for application in water splitting. Crystalline hematite nanorods (EG-alpha-Fe2O3) are fabricated by electrodeposition in Fe2+ precursor solution with the addition of ethylene glycol (EG) and followed by annealing at 450 degrees C. The nanorod hematite film fabricated by the modified electrodeposition approach exhibits a more uncompact structure than alpha-Fe2O3 obtained by directly electrodepositing on the FTO substrate. The optical and structural characteristics of the obtained film are also tested. The results infer that EG can tune the morphology of hematite and improve the photoabsorption in the visible light region due to its inducement of one-dimensional growth of crystal hematite. It also enhances the photoresponse activity of hematite in water splitting by improving the activities at the semiconductor/solution interface. The photocurrent density of EG-alpha-Fe2O3 nanorods increased to 0.24 mA cm(-2) at 1.4 V vs. RHE in 1 M KOH (pH = 13.6), almost 5 times higher than the original alpha-Fe2O3 (0.05 mA cm(-2), measured under the same conditions).
