In recent years,due to their superior chemical,mechanical and surface Raman scattering property,nanoporous metals,which are new types of functional materials with ultrahigh specific surface area and bi-continuous network at nano-scale,have been widely used in many fields such as catalysis,sensing,new energy and bio-medical engineering.In this paper,detailed review is carried out on some research works related to preparation,mechanical property and scale-sensitive performance of nanoporous metals, with an emphasis on scaling law,failure mechanism,surface effects and dealloying process,and some future directions are also pros-pected.
