Abstract

See full text

A metallic alloy includes Cu and one or more metals M selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni and Zn, wherein the alloy has a surface in the form of a vermiculated arrangement of irregular, nanoporous lands separated by troughs or channels. It can be made by contacting a precursor alloy including Cu, M and Al with a caustic liquid under conditions sufficient to remove the Al. Or, a metallic alloy includes Cu and one or more metals M selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni and Zn, wherein the one or more metals M in total constitute in a range of 3 at. % to 7 at. %, relative to the total of Cu and M. Both types of alloy can be used as an electrocatalyst in a water electrolyzer or a hydrogen fuel cell.
