METHOD FOR PRODUCING HYDROGEN BY WATER DISSOCIATION

摘要

The invention relates to a method for producing hydrogen from an aqueous medium containing an electron donor, a photosensitizer and a supported catalyst. The method is characterised in that the photosensitizer is a compound containing a porphyrin cycle bearing peripheral cationic groups non-conjugated with the porphyrin cycle, wherein said compound is not complexed with a metal and the reaction medium is subjected to a white light irradiation. The method can be used for obtaining hydrogen with a good yield, in particular from low intensity daylight.
