Electro-reduction of hydrogen peroxide on iron tetramethoxy phenyl porphyrin and lead sulfate electrodes with application in direct borohydride fuel cells

Electroreduction of hydrogen peroxide in acidic medium is reported onto carbon-supported iron tetramethoxy phenyl porphyrin (FeTMPP/C) as well as carbon-supported lead sulphate (PbSO4/C) electrodes. Both the catalytic electrodes can sustain electroreduction of hydrogen peroxide in direct borohydride fuel cells using hydrogen peroxide as oxidant but PbSO4/C electrode shows catalytic activity
