摘要

Abstract

F-PbO

electrode and polytetrafluoroethylene(PTFE) doped F-PbO

electrode(PTFE-F-PbO

) were prepared on a plexiglas sheet substrate by a series of procedure including chemical and electrochemical depositions. The electrochemical activities of these two electrodes for oxygen evolution(OE) reaction were examined by electrochemical tests.In comparison with F-PbO

PTFE-F-PbO

electrode exhibited larger active surface area and higher oxygen vacancy deficiency

which resulted in its higher electrocatalytic activity for OE.In addition

both exchange current density and activation energy of the electrodes for OE were calculated in terms of active surface area.The values of exchange current density and activation energy in 0.5 mol·L

-1

aqueous solution were 1.125×10

-3

mA·cm

-2

and 18.62 kJ·mol

-1

for PTFE-F-PbO

and 8.384×10

-4

mA·cm

-2

and 28.98 kJ·mol

-1

for F-PbO

respectively.Because these values are calculated on the basis of the active surface areas of the electrodes

the enhanced activity of PTFE-F-PbO

can be attributed to an increase in oxygen vacancy deficiency of PbO

due to doping by PTFE.The influence of PTFE adulteration on the activity of PbO

film electrode for OE was investigated in detail in this study.
