<string language="fre"><![CDATA[Hydrogen is
presented by some industrialists and managers as a potential pillar of the
ecological transition, particularly in the context of transport
(hydrogen-powered cars, hydrogen-powered trains, hydrogen-powered airplanes,
etc.), the storage of energy from intermittent renewable sources or in industry
(steel and chemical industries). Using hydrogen to decarbonize the economy only
makes sense if it is produced in a decarbonized way. In this context, this talk
will focus on hydrogen production from renewable sources, solar and water. The
performance (absorption of light, creation of photo-charges, their migration
and their reactivity with water) of the photoelectrodes depend strongly on the
chemistry, structure and microstructure of the materials used. All these
physical-chemical parameters can be trigger through a judicious control of
processing parameters. This talk will focus primarily on three different
processing approaches based on solution chemistry for synthesizing efficient
and durable photo-electrodes (Mo-BiVO4, TiO2 and CuO/Cu2O).
The performance of the photoelectrodes will be discussed as function of
structure, microstructure (porosity, particle size, thickness) and
hetero-structure. More importantly, for comparing the performance of the three TiO2
polymorphs, a judicious photoelectrodes’ manufacturing is developed in order to
solely measure the impact of the structure keeping all the other parameters
(porosity, thickness and particle size) constant.
