Journal ArticleDOI
Solar Water Splitting: Progress Using Hematite (α‐Fe2O3) Photoelectrodes
TL;DR: The latest efforts using advanced characterization techniques, particularly electrochemical impedance spectroscopy, are presented to define the obstacles that remain to be surmounted in order to fully exploit the potential of hematite for solar energy conversion.
Journal ArticleDOI
Highly active oxide photocathode for photoelectrochemical water reduction
Adriana Paracchino,Vincent Laporte,Kevin Sivula,Michael Grätzel,Elijah Thimsen,Elijah Thimsen +5 more
TL;DR: A highly active photocathode for solar H(2) production is presented, consisting of electrodeposited cuprous oxide, which was protected against photocathodic decomposition in water by nanolayers of Al-doped zinc oxide and titanium oxide and activated for hydrogen evolution with electroDeposited Pt nanoparticles.
Journal ArticleDOI
Semiconducting materials for photoelectrochemical energy conversion
Kevin Sivula,Roel van de Krol +1 more
TL;DR: Recently developed semiconductor materials for the direct conversion of light into fuels are scrutinized with respect to their atomic constitution, electronic structure and potential for practical performance as photoelectrodes in PEC cells.
Journal ArticleDOI
Light-Induced Water Splitting with Hematite: Improved Nanostructure and Iridium Oxide Catalysis†
TL;DR: Light-induced water splitting over iron oxide (hematite) has been achieved by using a particle-assisted deposition technique and IrO2-based surface catalysis and these photocurrents are unmatched by any other oxide-based photoanode.
Journal ArticleDOI
Probing the photoelectrochemical properties of hematite (α-Fe2O3) electrodes using hydrogen peroxide as a hole scavenger
TL;DR: In this article, the fate of photogenerated holes in photoelectrodes for water splitting was examined using H2O2 as an efficient hole scavenger, and all holes that arrived at the electrode/electrolyte interface were collected.
