Verfahren zur Herstellung von Wasserstoff |
摘要 |
<p>The invention relates to a process for production of hydrogen of high purity by photoelectrochemical means with low energy consumption. <??>The process is carried out in an electrochemical cell which comprises at least one anodic chamber with an anode and at least one cathodic chamber with a cathode, in which the two chambers are separated by an ion-exchange membrane, where: i) said anodic chamber contains an aqueous anodic solution which comprises the Fe<2+> ion, and said aqueous solution is adjusted to a pH less than or equal to 5; ii) a sacrificial substance is added to said anodic chamber; iii) said anodic solution is irradiated with ultraviolet light and/or visible light; iv) said cathodic chamber contains an aqueous cathodic solution which has a proton concentration equal to or higher than 10<-3> M; and v) electric current is fed between said anodic chamber and said cathodic chamber separated by said membrane, this membrane being a proton-selective ion-exchange membrane impermeable to the iron and impermeable to the sacrificial substance.</p> |
