Abstract: The present invention relates to an electrolysis device comprising an anode and a cathode, wherein the anode and the cathode each are an electrode comprising an electrically conductive support of which at least a part of the surface is covered by a metal deposit of copper, wherein the surface of the metal deposit is in an oxidized, sulfurated, selenated and/or tellurized form and the metal deposit has a specific surface area greater than or equal to 1 m2/g. The present invention relates also to a method for reducing CO2 into hydrocarbons using an electrolysis device according to the invention. The method according to the invention comprises: a) providing an electrolysis device according to the invention; b) exposing the cathode of said electrolysis device to a CO2-containing aqueous catholyte solution; c) exposing the anode of said electrolysis device to an aqueous anolyte solution; and d) applying an electrical current between the anode and the cathode in order to reduce the carbon dioxide into hydrocarbons.

Abstract: An adaptation device is provided for adapting an UV-Vis cuvette to perform in-situ spectroanalytical characterization of redox processes using gas species or solutes in a controlled atmosphere, the device configured to fit the open end of a UV-Vis cuvette intended to contain products to be measured during achievement of spectroanalytical measurements. The device comprises a main body configured to form a lid covering the opened end of the cuvette, the main body having a first part and a second part; a working, a counter and a reference electrode with removable parts at the respective ends of three conductors coming from outside and passing through the main body; a gas inlet to allow introduction of a gas the gas inlet having one aperture directed to the working electrode and second aperture directed to the bottom of the cuvette, a gas outlet intended to let the reactive gas in excess to flow out of the cuvette and an solution inlet tube for titration measurements.
