Investigation on the Adsorption and Photooxidation of Glycerol at TiO₂ Nanotubular Arrays

Figure 2

EIS results under irradiation: (a) Nyquist plots; (b) phase angle (empty symbols) and modulus (solid symbols) Bode plots; 𝐸=0.5 V, 𝜆=365nm. Blue symbols: in absence of glycerol. Red symbols: in presence of glycerol. Solid lines refer to the model fit.
