Coupling of electrocatalysts to photoabsorbers for solar fuels production
The direct transformation of sunlight into fuels and chemicals has attracted considerable attention for the potential impact on the storage of solar energies at large scales and the reduction of CO2 emissions. More than 80% of our current global energy con ...
EPFL2016Oxidatively Electrodeposited Thin-Film Transition Metal (Oxy)hydroxides as Oxygen Evolution Catalysts
Xile Hu, Laurent Liardet, Carlos Gilberto Morales Guio
The electrolysis of water to produce hydrogen and oxygen is a simple and attractive approach to store renewable energies in the form of chemical fuels. The oxygen evolution reaction (OER) is a complex four-electron process that constitutes the most energy- ...
American Chemical Society2016A facile nonpolar organic solution process of a nanostructured hematite photoanode with high efficiency and stability for water splitting
We present a facile nonpolar organic solution synthesis and processing method for water splitting photoanodes based on iron oxide with a relatively low sintering temperature (550 degrees C). The photocurrent of these photoanodes can reach 3.3 mA cm(-2) at ...
Royal Soc Chemistry2016Photoelectrochemical Hydrogen Production in Alkaline Solutions Using Cu2O Coated with Earth-Abundant Hydrogen Evolution Catalysts
Michael Graetzel, Xile Hu, Matthew Thomas Mayer, Stanley David Tilley, Laurent Liardet, Carlos Gilberto Morales Guio
The splitting of water into hydrogen and oxygen molecules using sunlight is an attractive method for solar energy storage. Until now, photoelectrochemical hydrogen evolution is mostly studied in acidic solutions, in which the hydrogen evolution is more fac ...
Wiley-Blackwell2015Redox flow battery and indirect water electrolysis
The progressive integration of renewable energy sources such as wind turbines and photovoltaic pannels in the current electrical network, and the rise of the electrical mobility, provoke a change of paradigm in the sector of energy management. The increasi ...
EPFL2015Amorphous molybdenum sulfides as hydrogen evolution catalysts
Xile Hu, Carlos Gilberto Morales Guio
Providing energy for a population projected to reach 9 billion people within the middle of this century is one of the most pressing societal issues. Burning fossil fuels at a rate and scale that satisfy our near-term demand will irreversibly damage the liv ...
American Chemical Society2014Hydrogen evolution from a copper(I) oxide photocathode coated with an amorphous molybdenum sulphide catalyst
Michael Graetzel, Xile Hu, Heron Vrubel, Stanley David Tilley, Carlos Gilberto Morales Guio
Concerns over climate change resulting from accumulation of anthropogenic carbon dioxide in the atmosphere and the uncertainty in the amount of recoverable fossil fuel reserves are driving forces for the development of renewable, carbon-neutral energy tech ...
Nature Publishing Group2014Growth and Activation of an Amorphous Molybdenum Sulfide Hydrogen Evolving Catalyst
Amorphous molybdenum sulfide films, prepared by electrodeposition, are a class of highly active catalysts for hydrogen evolution. The growth mechanism of the films and the true active species were unclear. Herein, we report a study of the growth and activa ...
American Chemical Society2013On the Texturing and Nanostructuring of Iron Oxide Photoanodes for Solar Water Splitting
The world needs to think about the after fossil fuel era and while the sun baths the earth with a tremendous amount of energy, man must learn how to harvest and store it in order to dispose of a continuous supply meeting his needs. Water photo-electrolysis ...
EPFL2013In situ photo-assisted deposition of MoS2 electrocatalyst onto zinc cadmium sulphide nanoparticle surfaces to construct an efficient photocatalyst for hydrogen generation
Michael Graetzel, Nripan Mathews
We reported herein a facile and scalable preparation process for MoS2-decorated ZnxCd1-xS hybrid photocatalysts for hydrogen generation. ZnxCd1-xS nanopowder was first prepared from commercially available precursors employing a solution based process. MoS2 ...
