Shape and size controlled synthesis of gold and silver porous nanostructures

We report the synthesis of shape and size controlled porous bimetallic nanostructures. Here we reported the use of silver nanostructures as sacrificial templates to transfer the nanostructures into hollow nanostructures. The perfect shapes and sizes of the ultimate Au hollow nanostructures depend on...
