Three-Dimensional Nanoporous Metallic Networks

Nanoporous metals are artificial. Therefore, their properties are a direct result of the preparation strategy. We introduce metals with networked nanoscale inner-architecture in three-dimensions. These networked-metals (`Netals`) express a peculiar interaction with light which is attributed to surface plasmons excitation. The interaction of noble-metal networks with the entire solar spectrum and their support on high hot-electron generation provides them with photo-catalytic abilities. Their combined properties of large-scale, purity, conductivity, transparency and higher surface area make them appealing from both fundamental-scientific and technological aspects.
