| Abstract: | The redox of molydates on a platinum electrode in H 2SO 4 solutions were studied.Molybdates were reduced to adsorbed hydrogen molybdenum bronzes on platinum electrode in H 2SO 4 solution during potential sweep cathodically.The hydrogen molybdenum bronzes were oxidized to different forms of hydrogen molybdenum bronzes with less hydrogen,depending on the H 2SO 4 concentration.Platinum electrode were modified by these hydrogen molybdenum bronzes.The electrocatalytic oxidation of methanol,formaldehyde and fomic acid on the modified platinum electrode and the catalytic mechanism were discussed. |
