Template‐Fabricated Gold Nanowires from Gas‐Phase Transport Reactions

Abstract

Aluminium oxide membranes are partially filled with solid nanowires of gold by chemical vapour transport (1000 to 650 °C) using iodine as the transport agent. The transport is due to the formation of gas‐phase AuI. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

Tree-like alumina nanopores generated in a non-steady-state anodization

“…2 It is expected that the as-obtained tree-like nanopores will be a new type of template for tree-like nanostructures possibly exhibiting novel size-and shape-dependent optical, electrical, magnetic, and mechanical properties, 17,18 which can be fabricated via electrodeposition 5,[22][23][24][25][26] or direct electroless infiltration. [27][28][29][30] As an example, some preliminary studies on gold nanotrees are described here. The pulsed electrodeposition resulted in rather uniform infiltration of gold into tree-like nanopores (see S1, S2 in ESI{).…”

A Chemical View of the Giant Au102(SR)44 (SR = P‐Mercaptobenzoic Acid) Cluster: Metalloid Aluminum and Gallium Clusters as Path Making Examples of This Novel Type Open Our Eyes for Structure and Bonding of Metalloid Aun(SR)m (n > m) Clusters

“…Our efforts to deposit gold within Al 2 O 3 nanotubes from the gas phase [53] may give one hint to this problem: Experimen-tal and DFT-based ΔH values for the species/compounds AuI (g) , AuI 3(g) und AuI (s) show that solid AuI is energetically very close to solid gold [54,55] [Equation (3)].
