Hydrogen gas is used in industrial processes. It has potential as a fuel and as a chemical raw material but large quantities are needed The present processes for obtaining hydrogen from hydrocarbons and/or producer gas or by electrolysis of water are generally not economical. The present invention provides a process for producing hydrogen from water using light as the energy source, and aqueous compositions used in said process. Said aqueous compositions comprise at least one photo-excitable reagent which absorbs light to donate an electron and produce hydrogen. The compositions also contain a solvent and at least one reagent selected from the group consisting of chain reaction agents which are free radical formers, and spectral sensitizers, and preferably at least one reagent of each of these two types. |
