Alloying and dealloying the surface of gold wires provide a general yet effective method to prepare highly durable Au nanocatalysts with mechanically robust core and high surface area nanoporous skin. Their potential as practically useful catalysts is showcased in the highly chemo-selective reduction of nitro compounds and azides using organosilanes as the reducing agents.
