Figure 6.17 Voltammetric profile for Pt(111), Pt(100), and Pt(110) electrodes in 0.2 M
CH 3 OH รพ 0.5 M H 2 SO 4 on electrode; scan rate 50 mV/s. (Data taken from Herrero et al. [1994].)
surface is very similar to that obtained with formic acid [Sun and Clavilier, 1987].
Owing to the similarities with formic acid, the following mechanism was proposed
for the oxidation of methanol:
active intermediate
methanol ! formaldehyde ! formic acid
CO 2
(6 : 17)
CO
