Thiol-terminated nanodiamond powders for support of gold nanoparticle catalysts

A New Approach to Generate Thiol-terminated SAMs on Gold

After the immersion of a gold substrate into an alkanethiol solution, thiols will spontaneously bind to the surface with the SH headgroups via a strong gold-sulfur interaction and typically adopt a standingup confi guration in the resulting closely packed monolayer, thus exposing the endgroups at the layer/medium interface. Tailoring the terminated chemical identity of self-organized assemblies...

Investigation of thiol derivatized gold nanoparticle sensors for gas analysis

TEM characterisation of novel supported silver and gold nanoparticle catalysts

This project is an extension of TEM work conducted on a previous AINSE funded project AINGRA08066, and aims to use the TEM, STEM/HAADF, EDS and plasmon imaging facilities at ANSTO to structurally characterize novel supported silver nanoparticle catalysts for ozone abatement, and supported gold catalysts for low temperature CO oxidation. The catalysts, fabricated at the University of Auckland, c...

Germanium Nanowire Arrays from Biotemplated Gold Nanoparticle Catalysts

Semiconductor nanowires (SCNWs) have been actively investigated due to their unique optoelectronic properties that are derived from their quasi one dimensional structure. However, the control over the crystallinity, diameter, and morphology of SCNWs is essential to achieve the desirable functional properties. Here we report a unique, bottom-up approach for the catalyzed growth of SCNWs via biol...
