• openAccess   Competitive Photoelectrochemical Methanol and Water Oxidation with Hematite Electrodes 

      Klahr, Benjamin; Gimenez, Sixto; Zandi, Omid; Fabregat-Santiago, Francisco; Hamann, Thomas ACS Publications (2015-03-24)
      Photocatalytic water and methanol oxidation were studied at thin film hematite electrodes synthesized by atomic layer deposition (ALD). Systematic photoelectrochemical characterization along with O2 evolution measurements ...
    • openAccess   Water Oxidation at Hematite Photoelectrodes with an Iridium-Based Catalyst 

      Badia Bou, Laura; Mas, Elena; Rodenas, Pau; Barea, Eva M; Fabregat-Santiago, Francisco; Gimenez, Sixto; Peris, Eduardo; Bisquert, Juan American Chemical Society (2013)
      The iridium complex [Cp*Ir(H2O)3](SO 4) was used as an organometallic source for the electrodeposition of iridium oxide onto Fe2O3. The new iridium-containing electrode allowed us to study the coupling between the ...
    • openAccess   Water oxidation at hematite photoelectrodes: the role of surface states 

      Klahr, Benjamin; Gimenez, Sixto; Fabregat-Santiago, Francisco; Hamann, Thomas; Bisquert, Juan American Chemical Society (2012)
      Hematite (α-Fe2O3) constitutes one of the most promising semiconductor materials for the conversion of sunlight into chemical fuels by water splitting. Its inherent drawbacks related to the long penetration depth of light ...
