The electrochemical properties of the Dawson-type heteropolyanion P₂W₁₈O₆₂^6- were studied in detail by cyclic voltammetry, alternating current (AC) voltammetry, and AC impedance. Cyclic voltammetry results revealed that P₂W₁₈O₆₂^6- possessed two pairs of reversible one-electron redox waves and two pairs of reversible two-electron redox waves in a solution containing 0.1 mol·L^-1 Na₂SO₄ and NaHSO₄ (pH 2.52). The peak potential and the peak current of the single-electron wave were independent of the solution pH while the peak potential of the two-electron wave shifted negatively, and the peak current decreased with an increase in solution pH. This indicated that the two-electron electrode process involved H⁺ and the involved H⁺ number was 2. AC impedance spectroscopy showed that the P₂W₁₈O₆₂^6- electrode process was fully controlled by diffusion and the diffusion coefficient (D_O) was 2.5×10^-6 cm²·s^-1. The cyclic voltammograms indicated that significant P₂W₁₈O₆₂^6- electrocatalysis towards O₂ reduction to H₂O₂ occurred as evidenced by the third wave pair and a catalytic efficiency of 300% were obtained. Application of P₂W₁₈O₆₂^6- in the degradation of nitrobenzene in the electro-Fenton-like system containing PW₁₁O₃₉Fe(III)(H₂O)^4- showed a remarkable improvement in terms of degradation efficiency.
