Nanoporous gold (NPG) has a long history of application[1].By electrochemical or chemical removal of Ag from AgAu alloy,the remaining gold undergoes a self-organization process forming a 3D bicontinuous network with interconnected ligaments.Due to its relatively high surface area,high conductivity,small size ligament and 3D bicontinuous porous structure,NPG has found its way in electrocatalysis[2],bio-sensors[3],fuel cells[4].By extending dealloy time[1] or thermal coarsening temperature[5],the structure of NPG can be easily tuned.
