• closedAccess   Carrier density and interfacial kinetics of mesoporous TiO2 in aqueous electrolyte determined by impedance spectroscopy 

      Gimenez, Sixto; Dunn, Halina K.; Rodenas, Pau; Fabregat-Santiago, Francisco; Miralles, Sara G.; Barea, Eva M; Trevisan, Roberto; Guerrero, Antonio; Bisquert, Juan Elsevier (2012)
      Water splitting at a semiconductor/solution interface with the only input of sunlight to generate hydrogen is one of the most attractive strategies to produce and store chemical energy. In the present study we have ...
    • openAccess   Harnessing infrared photons for photoelectrochemical hydrogen generation. A PbS quantum dot based "quasi-artificial leaf" 

      Trevisan, Roberto; Rodenas, Pau; González Pedro, Victoria; Sima, Cornelia; S. Sánchez, Rafael; Barea, Eva M; Mora-Sero, Ivan; Fabregat-Santiago, Francisco; Gimenez, Sixto American Chemical Society (2013)
      Hydrogen generation by using quantum dot (QD) based heterostructures has emerged as a promising strategy to develop artificial photosynthesis devices. In the present study, we sensitize mesoporous TiO2 electrodes with ...
    • closedAccess   Quantum Dot Based Heterostructures for Unassisted Photoelectrochemical Hydrogen Generation 

      Rodenas, Pau; Song, Taeseup; Sudhagar, P.; Marzari, Gabriela; Han, Hyungkyu; Badia Bou, Laura; Gimenez, Sixto; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Bisquert, Juan; Paik, Ungyu; Kang, Yong Soo Wiley (2013-02)
      TiO2 hollow nanowires (HNWs) and nanoparticles (NPs) constitute promising architectures for QDs sensitized photoanodes for H2 generation. We sensitize these structures with CdS/CdSe quantum dots by two different methods ...
    • 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 ...
