Area of Science:

  • Materials Science
  • Electrochemistry
  • Renewable Energy

Background:

  • Hematite (α-Fe2O3) is a promising photoanode material for solar water splitting.
  • Challenges include interfacial charge recombination and low electrical conductivity.

Purpose of the Study:

  • To introduce a titanium dioxide (TiO2) interlayer for hematite photoanodes.
  • To enhance photocurrent and electrical conductivity of hematite photoanodes.

Main Methods:

  • Fabrication of hematite nanoarray photoanodes with a TiO2 interlayer.
  • Characterization of photoelectrochemical performance under AM 1.5G illumination.
  • Investigation of TiO2 as a passivation layer and dopant source.

Main Results:

  • The TiO2 interlayer suppressed interfacial charge recombination.
  • Ti4+ incorporation into hematite improved electrical conductivity.
  • Dendritic nanostructure enhanced charge collection efficiency.
  • Achieved photocurrent of ~2.5 mA cm−2 at 1.23 V vs. RHE.
  • Photocurrent increased to ~3.1 mA cm−2 with an iron oxide hydroxide cocatalyst.

Conclusions:

  • The TiO2 interlayer effectively enhances hematite photoanode performance.
  • This strategy offers a pathway for improved solar water splitting devices.
  • Further optimization with cocatalysts significantly boosts efficiency.
