Synthesis of Silica – Gold Nanocomposites and their Porous Nanoparticles by In – Situ Approach, A. Kumar, V. L. Pushparaj, S. Murugesan, G. Viswanathan, R. J. Linhardt, O. Nalamasu and P. M. Ajayan, Langmuir, 22, 8631-8634, 2006.
We demonstrate the one-step synthesis of a silica-gold nanocomposite by simultaneous hydrolysis and reduction of gold chloride. The aminophenyl group was used as a reducing agent, and the trimethoxy silane group acts a precursor for the formation of silica. The porous gold nanoparticles were formed by etching out the silica-gold nanocomposite by hydrofluoric acid. The electron diffraction of porous gold nanoparticles showed that the particle are polycrystalline with FCC structure. The silica-gold nanocomposite exhibited nonlinear current-voltage behavior, and the porous gold nanoparticles displayed linear current-voltage behavior.;
