Reduction of perchlorate on rhodium and its specificity to surface crystallographic orientation

On the stability of perchlorate ions against reductive attacks in electrochemical systems and in the environment

“…In case of ICs/GAC, 97 % of the perchlorate ions were removed within 10 h at 90 °C. The experimental results also showed that FeOHSO 4 and Fe 2 O 3 nanoparticles have the function of perchlorate adsorption and play important roles in 4 …”

“…In contrast, in the electrochemical literature 4 ClO − are often considered to be very stable anions.…”

“…In such studies, it is tacitly assumed that the reduction of the 4 ClO − is not taking place under the actual experimental conditions. However, evidence for the occurrence of the reduction process has been reported for Rh [1][2][3][4][5], Pt [6][7][8][9], WC [10], Al [11], Ti [12], Ir [13], Ru [14], Re [15], Tc [16], and Sn [17] electrodes.…”

“…A nanostructured conducting copolymer poly(anilineco-o-aminophenol) (PANOA) was electrochemically synthesized on a glassy carbon (GC) electrode and its redox and anion exchange properties for perchlorate removal were investigated by cyclic voltammetry, FTIR, and X-ray photoelectron spectroscopy (XPS). FTIR spectra demonstrated that 4 …”

“…The equations given above involve the coupling of the anodic dissolution of the metal with two cathodic processes: discharge of protons and reduction of 4 …”
