Described is a monolithic catalyst system ( 1 ) for the cleavage of water into hydrogen and oxygen with the aid of light, comprising a first photoactive material ( 50 ) capable by itself or together with one or more auxiliary catalysts when irradiated with light having a wavelength ≧420 nm of generating oxygen and protons from water, and a second photoactive material ( 60 ) capable by itself or together one or more auxiliary catalysts ( 92 ) when irradiated with light having a wavelength ≧420 nm of reducing protons in water to hydrogen, the first photoactive material ( 50 ) and second photoactive material ( 60 ) being in electrical contact via one or more electron-conducting materials ( 30, 20, 40, 60 a ) the system being in that characterized in that a load or an electric consumer is interposed in between at least one electron-conducting material. Likewise described is a method of generating oxygen, hydrogen and electricity from water using the catalyst system. |
