A. Hilmi et al., ELECTROCATALYTIC OXIDATION OF ALIPHATIC DIOLS ON PLATINUM AND GOLD .1. EFFECTS OF CHAIN-LENGTH AND ISOMERIC POSITION, Journal of electroanalytical chemistry [1992], 380(1-2), 1995, pp. 177-184
The electrochemical reactivity of propanediol, butanediol, pentanediol
, hexanediol and heptanediol, on polycrystalline platinum and gold ele
ctrodes, was studied in acid and alkaline media. The effect of the num
ber of carbon atoms, i.e. the chain length, was observed. The apparent
energies of activation were evaluated systematically and discussed in
relation to the molecular structure of the different diols. In the ca
se of the butanediol isomers, an effect of the alcohol group positions
on the activation energy and reaction mechanisms was clearly shown.
