Abstract
Hydrogen is generated from water containing acid by passing electric current through it, using as the cathode a semiconductor exposed to light and having a transition metal metallocenophane compound attached to the surface of the cathode by means of a polymer.
Claims10
A process for generating hydrogen from water containing an acid by passing an electric current through the water using a cathode which is a semiconductor exposed to light, said process characterized in that a transition metal metallocenophane compound is attached to the surface of the cathode by means of a polymer.
A process for generating hydrogen from water containing boron trifluoride hydrate by passing an electric current through the water with a p-type silicon semiconductor cathode which is exposed to sunlight and which is coated with a polymer chemically bonded to [1.1]ferrocenophane.
