Abstract

Abstract : Hematite nanorods doped with ruthenium were successfully deposited on fluorine doped tin oxide (FTO) glass substrates using aqueous chemical growth. Using complementary surface/interface investigation techniques, the Ru incorporation in the Ru- α -Fe2 O3 nanorods was evidenced. The optical band gap was found to be Ru doping concentration dependent: varying from 2.32 (2) to 2.47 (2) eV. These band gap values are well suited for the targeted water splitting process without application of an external bias.
