Research Progress in Fabrication of Nanoporous Metal Materials

Many methods can be used to fabricate nanoporous materials,dealloying method and template method are discribed by taking porous gold as an example.The template method is relatively convenient,and highly ordered nanostructures can be obtained by this method,moreover,the sizes of the pores can be controlled easily.Several templates can be employed,such as AAO template,PC template,opal and inverse opal template,hydrogen bubbles template,an so on.Therefore the method is used extensively.
