Disclosed is an electrochemical method for continuous regeneration of a Pt.sup.IV oxidant to furnish overall electrochemical methane oxidation. Cl-adsorbed Pt electrodes catalyze facile oxidation of Pt.sup.II to Pt.sup.IV without concomitant methanol oxidation. Exploiting this electrochemistry, the Pt.sup.II/IV ratio in solution is maintained via in situ monitoring of the solution potential coupled with dynamic modulation of the electric current. Remarkably, this method leads to sustained methane oxidation catalysis with ˜70% selectivity for methanol.
