Final Technical Report
We adapted and refined a synthesis of gold nanoparticles of type, Au101(PPh3)21Cl5 (Au101). In our hands, this method routinely gave fairly high yields of Au101 NPs. These NPs were characterized using several techniques, including TEM, AFM/STM and various NMR measurements, including solid state methods. We also used a simpler citrate-based preparation of Au NPs. We immobilized the Au NPs on carbon and characterized their electrochemical behavior. In addition, we prepared and characterized tin oxide NPs that were capped with phosphonic acid capping ligands. Our goal in this part of the project was to expand the NMR methods available to study ligand complexation in non-metallic NP materials that may be of interest as electrochemical materials. The use of tin oxide as a host material for tin metal that could be used to alloy of Li in battery anodes was the motivation for our interest in these types of materials.
