The invention relates to a photocatalytic carbon dioxide reduction method carried out in liquid and/or gas phase under irradiation, using a photocatalyst containing a first semiconductor, particles comprising one or more metallic-state elements M, and a second semiconductor SC, wherein the method is carried out by contacting a feedstock containing the COand at least one sacrificial compound with the photocatalyst, then irradiating the photocatalyst such that the COis reduced, and oxidising the sacrificial compound in order to produce an effluent containing at least in part C1 or above carbon molecules other than CO.

Photocatalytic carbon dioxide reduction method using a photocatalyst in the form of a porous monolith

Process for preparing a porous monolith comprising between 10% and 100% by weight of a semiconductor relative to the total weight of the porous monolith, which process comprises the following steps:

Process for preparing a monolith with multimodal porosity

The invention relates to a porous monolith comprising between 20 wt.-% and 70 wt.-% TiO 2 relative to the total weight of the monolith, and between 30 wt.-% and 80 wt.-% a refractory oxide, selected from silica, alumina or silica-alumina, relative to the total weight of the monolith, characterized in that said porous monolith has a bulk density of less than 0.19 g/mL.

Porous monolith containing TiOand method for the production thereof

A miniaturized electrochemical cell and a method for making it are provided. The method includes preparing at least one inner electrode of an electron conducting or semi-conducting material M; providing a hollow support made of an electrically insulating material Mand having at least one internal hollow channel; depositing on the external surface of the support a layer of an electrically conducting material M; forming a template of colloidal particles of an electrically insulating material M, on the Mlayer; depositing a layer of an electrically conducting material Mon the Mlayer; depositing a layer Lof an electron conducting or semi-conducting material Mon the Mlayer, introducing the at least one inner electrode into the at least one internal hollow channel of the obtained structure; stabilizing the structure at its two open ends with an electrically insulating material M; and removing M, M, Mand Mmaterials.

The invention relates to nanometric or mesoscopic dissymmetric particles, and to a method for preparing the same. The particles have an inorganic part A and a spherical organic part B bound by physicochemical or covalent interactions. Material A is a metal oxide, a metal or a metal chalcogenide. Material B is a polymer consisting of recurrent units derived from a vinyl compound. The particles are obtained by modifying the surface of material A particles with a coupling agent C having a function Fwhich exhibits affinity for the polymer, and contacting the modified inorganic particles with the precursor(s) of the polymer B, in the presence of a free radical initiator and of a surfactant in solution in a solvent.
