Nanoporous Morphology of Dealloyed Parent Phase Ordered and Disordered Cu3Au Alloys

Nanoporous gold (NPG) has found revolutionary applications in energy and biomedicine-related fields. Despite this, there is little understanding of the detailed self-organization process during dealloying, which develops the bicontinuous solid-void morphology. By understanding that NPG adopts the same structure and orientation as its parent phase material (PPM), comparing the NPG structures created from compositionally identical,
