A dip coating process for large area silicon-doped high performance hematite photoanodes

Michael Graetzel, Artur Braun, Yelin Hu, Florent Alexandre Boudoire

A facile and low-cost dip-coating process for the deposition of silicon doped hematite films (Si:alpha-Fe2O3) for hydrogen production by solar water splitting in photo-electrochemical cells (PEC) is presented. The precursors include iron nitrate, oleic aci ...

Identifying champion nanostructures for solar water-splitting

Michael Graetzel, Francesco Stellacci, Cécile Hébert, Kislon Voitchovsky, Maurin Cornuz, Scott Charles Warren

Charge transport in nanoparticle-based materials underlies many emerging energy-conversion technologies, yet assessing the impact of nanometre-scale structure on charge transport across micrometre-scale distances remains a challenge. Here we develop an app ...

Passivating surface states on water splitting hematite photoanodes with alumina overlayers

Michael Graetzel, Kevin Sivula, Nicolas Tétreault, Thomas Moehl, Florian Le Formal, Maurin Cornuz

Hematite is a promising material for inexpensive solar energy conversion via water splitting but has been limited by the large overpotential (0.5-0.6 V) that must be applied to afford high water oxidation photocurrent. This has conventionally been addresse ...

Highly active oxide photocathode for photoelectrochemical water reduction

Michael Graetzel, Kevin Sivula, Vincent Laporte, Adriana Paracchino

A clean and efficient way to overcome the limited supply of fossil fuels and the greenhouse effect is the production of hydrogen fuel from sunlight and water through the semiconductor/water junction of a photoelectrochemical cell, where energy collection a ...

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 ...

Photoelectrochemical Water Splitting with Mesoporous Hematite Prepared by a Solution-Based Colloidal Approach

Michael Graetzel, Kevin Sivula, Florian Le Formal

Sustainable hydrogen production through photoelectrochemical water splitting using hematite (alpha-Fe2O3) is a promising approach for the chemical storage of solar energy, but is complicated by the material's nonoptimal optoelectronic properties. Nanostruc ...

Controlling photo-activity of solution-processed hematite electrodes for solar water splitting

Michael Graetzel, Kevin Sivula, Jérémie Minh-Châu Brillet

Hematite is a promising material for solar energy conversion via photo-electrochemical water splitting. However, the precise control of substitutional doping and nanometer feature size is important for high photon harvesting efficiency. Doped and nanostruc ...

Controlling Photoactivity in Ultrathin Hematite Films for Solar Water-Splitting

Michael Graetzel, Kevin Sivula, Florian Le Formal

A promising route to increase the performance of hematite (alpha-Fe2O3) photoelectrodes for solar hydrogen production through water-splitting is to use an extremely thin layer of this visible light absorber on a nanostructured scaffold. However, the typica ...

Electrospinning of diphenylalanine nanotubes

Klaus Kern, Alexander Bittner, Sebastian Loscher

Electrospinning from concentrated diphenylalanine solutions in a low-boiling-point solvent results in tubes that are chemically identical to self-assembled tubes, but show different morphologies, especially extreme lengths. Electrospinning of tubes offers ...
