摘要

In this report, NiCo2Sx nanostructures are directly synthesized on stainless steel (SS) substrates by a facile electrodeposition method in addition to a post-vulcanization process. The binder free NiCo2Sx/SS electrode shows high electrocatalytic activity for methanol oxidation compared with NiSx and CoSx. The prepared NiCo2Sx is a promising non-platinum electrocatalyst for direct methanol fuel cells.
