Research Topics

1) Synthesis and characterization of metal nanoparticles supported on different substrates. In recent years considerable attention has been drawn to the possibility of deposition of metal nanoparticles onto substrates (conducting or not conducting) due to its great importance in the fabrication of practical devices such as heterogeneous catalytic systems to be used under batch or continuous-flow conditions or biomaterials.

Several methods have been reported to accomplish this purpose; among these chemical and electrochemical synthesis have been proved to be very striking because of the simple instrumentation needed and the capability to readily control the size and morphology of the as-deposited nanostructures through adjusting the experimental parameters. The aim is to provide the necessary tools for the preparation of non conductive (i.e. silica, alumina, titania hydroxyapatite, hydrotalcite) or conductive (i.e. Indium Tin Oxide (ITO), Glassy Carbon (GC)) surfaces modified with metal nanoparticles. The effect of some variables as the choice of precursor used, the presence of additives, the kind of functionalized substrate, the electrolyte employed or the electrodeposition conditions on the nanoparticles size and distribution have been investigated. These studies could offer a new approach to cost-effective way to prepare supported metal nanoparticles.

2) Synthesis and application of environmentally safer fluorinated molecules.

3) Synthesis and application of ionic liquids.
