Summary:

We confirmed that the TiO2 nanorods array fabricated using TiCl4 for 150 minutes can clearly proceed the oxidation reaction, which act as catalyst to facilitate the oxidation reaction from thiol to disulfide in 2-thiophenebenzaldehyde and alcohol to aldehyde in 2-mercaptoethanol. Moreover, we could confirm that many defects formed inside this structure can enhance the oxidation reaction, which can clearly act as better catalyst than TiO2 nano-particle and facet-less TiO2 nanorods array. As a result, we found that through the oxidation reaction using two molecules on three distinct TiO2 samples, the longer facet clearly affects catalytic oxidation reaction.
