Description
Summary:Using inexpensive and environmentally friendly Mn oxide, a very simple method to synthesize an efficient and stable water-oxidizing electrode on the surface of a fluorine doped tin oxide electrode was reported. The electrode at pH = 13 yields a current density of 1 mA cm at an overpotential of 450 mV, which is promising to be used as an anode in water-splitting systems. In higher overpotential (800 mV), a current density of 7 mA cm was observed. Proposed different states of the growth of layered Mn oxide on the surface of FTO based on SEM images were also discussed.
