Abstract:
1. A process for generating hydrogen and oxygen from water, comprising the step of bringing water into contact with at least one crystalline silicide under simultaneous application of light, wherein the at least one silicide is an electrode that is in electric contact with at least one counter electrode by an electrolyte, wherein the counter electrode can be a metal, a transition metal, a metal oxide, a transition metal oxide, a non-metallic structure and/or a mixed structure, wherein the at least one silicide belongs to non-metallic silicides, such as boron silicide, also called silicon tetraboride (B 4 Si), compounds that contain silicon and correspond to the molecular formula RSi x where R represents an organic, organometallic and/or inorganic residue or a mixture thereof and Si stands for the element silicon (silicon), with an increasing number of atoms X>0.
