Embodiment Construction

[0061] figure 1 Show the preparation of hydrogen (H) from water phase 2 and light source 3 in background technology 2 gas) device 1. The device 1 comprises a front wall 4 which allows the passage of photons from a light source 3 to illuminate a photocatalytic system 9 in contact with the aqueous phase 2 . The device also comprises a rear wall 5, eg made of a suitable polymer. Of course, the device 1 also includes top, bottom and side walls together with front and rear walls, forming a waterproof device (generator). For example, the front wall 4 may be made of glass, although any suitable material that enables photons from the light source 3 to illuminate the photocatalytic system 9 in contact with the aqueous phase 2 is encompassed by the invention.

[0062] The aqueous phase 2 soaks an anode 6 (such as a carbon anode 6 ) containing a photoenzyme, such as PSII as a photocatalytic system 9 , connected via a voltage regulator 7 to a cathode submerged in the same aqueous phase...

Abstract

The invention relates to a photocatalytic aqueous-phase-dissociation device for producing gaseous hydrogen, said device being arranged such that at least one photocatalytic system that is in contact with the aqueous phase can be irradiated by a light source in order to produce gaseous oxygen, electrons and protons by means of a reaction involving the oxidation of the aqueous phase at an electron capture means. The device comprises: a first zone containing the aqueous phase; and a proton reduction means arranged to perform a reaction involving the reduction of the protons with the electrons soas to produce gaseous hydrogen, said proton reduction means being a proton exchange interface having a front face oriented towards the electron capture means and a back face, in which only the back face of the proton exchange interface comprises at least one catalyst and / or at least one catalytic system.

Description

technical field [0001] The present invention relates to a photocatalytic device for decomposing an aqueous phase to produce hydrogen, the device shown being arranged in such a way that at least one photocatalytic system in contact with said aqueous phase can be irradiated by a light source through an oxidation reaction in said aqueous phase , producing oxygen, electrons and protons at an electron capture device comprising: [0002] a first zone comprising said aqueous phase, and [0003] means for reducing said protons by said electrons to perform said reduction reaction on said protons to produce hydrogen. Background technique [0004] In the present invention, the term "photocatalytic system" refers to a photocatalyst comprising at least one photo-enzyme and / or its coenzyme and any oxidation reaction in water phase. [0005] In the present invention, the term "aqueous phase" refers to a phase containing only water or any phase containing water and at least one additive, ...
