Microplasma synthesis of titanium dioxide nanowires

In this work we developed a process to produce titanium dioxide nanowires through microplasma synthesis in atmospheric conditions. The titanium dioxide nanowires grow on the surface of the titanium anode. During initial synthesis, free chlorine anions form and migrate to the Ti anode creating various Ti-Cl complexes (TiCl4). H2O2 molecules are decomposed at the titanium anode to form OH species that react with the Ti-Cl complexes forming TiO2 nanowires. The microplasma environment is ideal for creating titanium dioxide nanowires through the creation of several reactive species that typically require reaching high temperatures (>300 degrees C). The anode and cathode materials were varied along with the liquid electrode composition for determining the reaction mechanisms involved and analyzed through EDS and XRD techniques.
