“…The iron alloy films were deposited on conductive fluorinedoped tin oxide (FTO) glass substrate by DC magnetron sputtering technique and the target was a commercial available iron disk with chips of desired doping element pasted on the surface. The concentration of doping element (M, M = Sn or Ge) is defined as M/(M+Fe) mole ratios were tuned by the relative areas of the pasted chips [24] and determined by EDS. Prior to sputtering deposition, FTO substrates were sonically cleaned using acetone, ethanol, and deionized water each for 10 min in that sequence.…”

Sn- or Ge-doped hematite thin films were fabricated by annealing alloyed films for the purpose of photoelectrochemical (PEC) water splitting. The alloyed films were deposited on FTO glass by magnetron sputtering and their compositions were controlled by the target. The morphology, crystalline structure, optical properties, and photocatalytic activities have been investigated. The SEM observation showed that uniform, large area arrays of nanoflakes formed after thermal oxidation. The incorporation of doping elements into the hematite structure was confirmed by XRD. The photocurrent density-voltage characterization illustrated that the nanoflake films of Sn-doped hematite exhibited high PEC performance and the Sn concentration was optimized about 5%. The dopedGe4+ions were proposed to occupy the empty octahedral holes and their effect on PEC performance of hematite is smaller than that of tin ions.

“…The iron-base alloy films were deposited on conductive fluorine-doped tin oxide (FTO) glass substrate by radio frequency (RC) magnetron sputtering technique and the target was a commercial available Fe 2 O 3 disk with chips of CeO 2 (round tablets with a diameter of 2mm and a thickness of 1mm) pasted on the surface. The concentration of doping element was defined as Ce/(Ce+Fe) atom ratio, which was tuned by the relative area of the pasted chips [18]. Prior to sputtering deposition, FTO substrates were sonically cleaned using acetone, ethanol and de-ionized water each for 15min in that sequence.…”

Hematite is one of the most promising photoanodes for water splitting, but its photoelectrochemical (PEC) efficiency is still low. This work proved that the PEC efficiency of hematite can be improved by Ce doping. The Ce doped hematite was successfully prepared by co-sputtering CeO2 and Fe2O3, and followed by thermal oxidation treatment. The results of J-V test showed that the photocurrent of 5 at.% Ce doped α-Fe2O3 film can reached 1.35mA/cm2 in 1 M NaOH (pH=13.6) at 1.23V vs. NHE, which is nearly 15 times higher than the undoped one. The enhancement of PEC efficiency was proved by the enhancement of absorbance of visible light, as well as increased carrier density after Ce doping.
