Simultaneous production of hydrogen and oxygen from water |
May 10, 1983 |
| A method for the simultaneous production of hydrogen and oxygen from water by the visible light irradiation of a water solution containing photosensitizer, an electron relay and a suitable combination of redox catalysts. |
| 4381978 |
Photoelectrochemical system and a method of using the same |
May 3, 1983 |
| A photoelectrochemical system for conducting endoergic chemical processes driven by light energy. This system consists essentially of an illuminated halfcell and a darkened halfcell joined via electrodes and an external circuit to allow for the transport of electrons. Also, the said half |

Photolytic production of hydrogen from water |
January 4, 1983 |
| The photodissociation of water into hydrogen gas is mediated by a catalytic dispersion of fine metal particles. This dispersion is stabilized by polymers of alkylene glycols which are adsorptive to said particles and which act as protective agents in solution. |
