Mechanism for Formation of Pt Nanowires in Mesoporous Silica Templates 

Isolation and Characterization of Metal/Alloy Nanowires Free from the Silica Supports 

Extraction of nanowires from mesoporous supports is important and desirable for their application as a building block for electronic devices and catalyst preparation. In addition, more detailed characterization of metal/alloy nanowires is available by their extraction from the sihca templates. Isolation of the Pt nanowires from mesoporous templates has also been tried by dissolving FSM-16 and HMM-1 with aqueous HF or NaOH solution, but the nanowires were readily decomposed into Pt aggregates. However, the Pt nanowires were successfully extracted as their original forms from the sihca templates using HF and [NBu4]Cl as a surfactant in a benzene/ethanol solution. It is reasonably implied that the extracted wires are
