Porous Nanostructured Materials

A large variety of electrochemical methods can be used to obtain porous nanostructures. The first part of this chapter deals with bottom-up methods such as dynamic bubble templating and direct deposition of porous layers, completed with post-deposition surface modification methods. The second part of the chapter yields an overview on dealloying, which is a top-down method to obtain porous nanostructures. In each part, combinative routes by applying various electrochemical and non-electrochemical methods are also be presented.
