SYNTHESIS OF NOBLE METAL SULPHIDE CATALYSTS IN A SULPHIDE ION-FREE AQUE OUS ENVIRONMENT

摘要

The invention is relative to a catalyst, in particular to a noble metal sulphide electrocatalyst, obtained by reacting the precursor of at least one noble metal with a thionic species in an aqueous environment essentially fre e of sulphide ions, and to a method for producing the same.
