Effect of Ionic Liquid Electrolyte on Electrochemical and Electrocatalytical Behaviours of Tri-Iron Cluster
Asian Journal of Chemistry,
Vol. 22 No. 1 (2010): Vol 22 Issue 1, 2010
Abstract
The tri-iron cluster, [Fe3(μ3-S)2(CO)9], has been reported as a
catalysis to proton reduction at low overpotential. In this paper, the
electrochemical behaviour of the tri-iron cluster and its catalytic effect
on hydrogen evolution were investigated further by using ionic liquid
(1-dodecane-3-methylimidazolium tetrafluoroborate, IL) as electrolyte
in dichloromethane, considering that IL has unique chemical and physical
properties. In contrast to the conventional electrolytes (such as [NBu4]BF4),
the IL electrolyte increases the stability of the monoanionic radical generated
from the first reduction and the electrocatalytic efficiency on proton
reduction has also been improved.
