Abstract: Two shapes of TiO2 nanomaterial will largely
affect the catalytic activity. TiO2 nanoparticles (NPs) and
TiO2 nanofibers (NFs) were used to investigate the effect
of shape on catalytic activities and get the optimum shape
of catalysis. Electrochemical behaviors of two modified
electrodes by TiO2 nanomaterial were evaluated by cyclic
voltammetry and electrochemical impedance spectroscopy.
Various electrochemical parameters such as electrode
surface area and electron-transfer rate constant were also
studied and calculated in the aqueous solution. Results
showed that the response of NF is better than NP for
electrooxidation of hydroquinone (HQ). The different
electrochemical response of TiO2 is related to the various
morphological structures, so controlling the shape and
structure of nanomaterial is very important factor which
is because of the powerful correlation between these parameters
and their optical, catalytic and electrical properties.
