Claim 0:
1. A composite electrode, comprising:
a stainless steel substrate; and
a plurality of silicon-containing nanostructures extending from the stainless steel substrate,
wherein:
said stainless steel substrate is a HF-treated stainless steel substrate,
said substrate is devoid of an externally added catalyst material,
said plurality of silicon-containing nanostructures form a three-dimensional network in which at least a portion of said plurality of silicon-containing nanostructures are fused with at least one other silicon-containing nanostructure, and
in at least a portion, or in all, of said plurality of silicon-containing nanostructures, each of said silicon-containing nanostructures:
is devoid of said externally added catalyst material;
is devoid of a noble metal;
comprises copper along a longitudinal direction of said silicon-containing nanostructures at an atomic ratio of 0.1%±0.05% relative to silicon, said copper originating from said HF-treated stainless steel substrate; and
comprises nickel silicide along a longitudinal direction of said silicon-containing nanostructures.
