Description
  • The mechanism of the Co(II) catalytic electroreduction of water insoluble CoR2 salt in the presence of cysteine (H2L +/-) was developed. CoR2 = cobalt( II) cyclohexylbutyrate is the component of a carbon paste electrode. Electrode surface consecutive reactions are: ( a) fast ( equilibrium) reaction of the CoR2 (H2L +/-)(ads) complex formation, (b) rate-determining reversible reaction of the promoting process of CoR(Ac+) complex formation, (c) rate-determining irreversible reaction of the electroactive CoR(Ac)(H2L +/-)(ads) complex formation with ligand-induced adsorption, and (d) fast irreversible reaction of the CoR(Ac)(H2L +/-)(ads) electroreduction. Reactions ( a, b) connected with CoR2 dissolution and reactions ( c, d) connected with CoR2 electroreduction are catalyzed by H2L +/-)(ads). Regeneration of (H2L +/-)(ads) ( reactions %22b, d%22) and accumulation of atomic Co( 0) ( reaction %22d%22) take place. Experimental data [Sugawara et al., Bioelectrochem Bioenergetics 26: 469, 1991]:
