title: Nanoporous Metal Papers for Scalable Hierarchical Electrode.
abstract: Nanoporous metals similar to paper in formare developed using Japanese washi paper as a template to create hierarchical porous electrodes. This method is used to create a trimodal -nanoporous Au electrode, as a well as a hierarchical NiMn electrode that achieves high electrochemical capacitance and a rapid rate of oxygen evolution.
