| Abstract: | The conductive polymer poly(neutral red) polymerized on a graphite electrode (PNR/graphite) as a support material was used
for catalytic oxidation of ethanol in acidic solution and investigated by electrochemical methods. Pt particles loaded on
the surface of PNR/graphite electrode exhibited higher electrocatalytic activity for ethanol oxidation in comparison with
Pt particles supported directly on graphite. With the equivalent loading mass of Pt catalyst, the special activity (S
A
) at peak a of the Pt/PNR/graphite electrode polymerized for 10 cycles in 5 × 10−4 M NR + 0.5 M H2SO4 solution is 3,478 A C−1 and about 2.20 times higher than that of the Pt/graphite electrode (1,582 A C−1). The results show that the electrochemical performance of Pt catalyst for ethanol oxidation is improved by the addition
of PNR |
