Title (EN) PHOTOCHEMICAL ELECTRODE
(FR) ELECTRODE PHOTOCHIMIQUE
Abstract:
(EN) Photochemical electrode can decompose water when irradiated with visible light and consists of red mercuric sulphide blackened by iodide treatment as a coating on a platinum mesh. A cell for electrolysing water by the action of light comprises said photochemical electrode (1), a counter-electrode (20), both electrodes being connected by an external circuit, and an aqueous sodium nitrate solution (9). The irradiation system consists of a Xenon lamp (34), lenses (30a, 30b) and a light filter (32).
(FR) Une electrode photochimique peut decomposer l"eau lorsqu"elle est irradiee avec de la lumiere visible et consiste en cinabre noirci par traitement au iodure sous forme de revetement sur une maille de platine. Une cellule pour electrolyser l"eau par l"action de la lumiere comprend ladite electrode photochimique (1), une contre-electrode (20), les deux electrodes etant connectees par un circuit externe, et une solution aqueuse de nitrate de sodium (9). Le systeme d"irradiation consiste en une lampe au Xenon (34), des lentilles (30a, 30b) et un filtre de lumiere (32).
