CATALYSEURS MOLÉCULAIRES MÉTAL-OXO PERMETTANT DE GÉNÉRER DE L'HYDROGÈNE À PARTIR D'EAU
Abstract:

". In embodiments of the invention, water, such as tap water containing electrolyte or straight sea water can be subject to an electric potential of between 1.0 V and 1.4 V relative to the standard hydrogen electrode, which at pH 7 corresponds to an overpotential of 0.6 to 1.0 V, with the result being, among other things, the generation of hydrogen with an optimal turnover frequency of ca. 1.5 million mol H
