Abstract
During S2O82- electrosynthesis, as sufficiently high potentials, a Pt anode in the SO42- soln. is covered by adsorbed SO42- species, the oxide-covered Pt becoming limited to isolated patches. The adsorption was obsd. by detns. of current efficiencies and potentials as a function of the concn. of S-contg. species at const. temp. and at various const. c.ds. The adsorbed SO42- essentially do not participate further in S2O82- formation, and SO42-, not HSO4-, are discharged on the SO42-covered areas of the electrode. The intermediates are formed in a nonadsorbed state and must be considered to be free radicals. [on SciFinder (R)]
