Electrodeposited Benzothiazole Phthalocyanines for Corrosion Inhibition of Aluminium in Acidic Medium

Figure 2

(a) Cyclic voltammogram of complex 1 in DCM containing 0.1 mol·dm⁻³ TBABF₄ at scan rate = 100 mV/s, concentration ∼1 × 10⁻⁴ mol·dm⁻³, and electrode = glassy carbon. (b) Evolution of the cyclic voltammograms of complex 2 in DCM containing 0.1 mol·dm⁻³ TBABF₄ during repeated successive scans (only 8 scans are shown), scan rate = 100 mV/s, concentration ∼1 × 10⁻⁴ mol·dm⁻³, and electrode = Al coupon. Inserted is the cyclic voltammogram of blank (without complex 2).
