Photo-assisted electrodeposition of cobalt-phosphate (Co-Pi) catalyst on hematite photoanodes for solar water oxidation

Michael Graetzel, Kevin Sivula, Maurin Cornuz

A photo-assisted electrodeposition approach was used to deposit a cobalt-phosphate water oxidation catalyst ("Co-Pi") onto recently improved dendritic mesostructures of alpha-Fe2O3. A comparison between this approach, electrodeposition of Co-Pi, and Co2+ w ...

Light-Induced Water Splitting with Hematite: Improved Nanostructure and Iridium Oxide Catalysis

Michael Graetzel, Kevin Sivula, Stanley David Tilley, Maurin Cornuz

Revved-up rust! Light-induced water splitting over iron oxide (hematite) has been achieved by using a particle-assisted deposition technique and IrO2-based surface catalysis. Photocurrents in excess of 3 mA cm-2 were obtained at +1.23 V versus the reversib ...

Examining architectures of photoanode-photovoltaic tandem cells for solar water splitting

Michael Graetzel, Kevin Sivula, Jun Ho Yum, Florian Le Formal, Maurin Cornuz, Jérémie Minh-Châu Brillet

Given the limitations of the materials available for photoelectrochemical water splitting, a multiphoton (tandem) approach is required to convert solar energy into hydrogen efficiently and durably. Here we investigate a promising system consisting of a hem ...

Preferential Orientation in Hematite Films for Solar Hydrogen Production via Water Splitting

Michael Graetzel, Kevin Sivula, Maurin Cornuz

The state-of-the-art performance, obtained through the reduction of precursor gas residence time in hematite photoanodes produced by APCVD, is explained in this report by an enhanced preferential orientation of the highly conductive crystal planes perpendi ...
