Use of Material, Especially an Eutectic One, as an Active Layer in an Electrode and an Electrode Comprising an Active Layer of Material, Especially an Eutectic One

摘要

The invention relates to the use of a material selected from the group comprising: an eutectic, subeutectic, hypereutectic, monotectic, submonotectic, hypermonotectic, eutectoidal, subeutectoidal and hypereutectoidal material or a material being a product of a spinodal decomposition as an active layer in an electrode, especially in the photoanode for photoelectrochemical cells.;The invention also includes an electrode, especially a photoanode for photoelectrochemical cells, comprising at least an active layer and an electric contact, optionally a contact layer situated between the active layer and the electric contact, characterised in that the active layer (1) made of a material selected from the group including: an eutectic, subeutectic, hypereutectic, monotectic, submonotectic, hypermonotectic, eutectoidal, subeutectoidal and hypereutectoidal material or a material being a product of spinodal decomposition.
