4.3.2.5 Selectivity Depending on Electrode
Materials
There are many examples of electrode materials
that greatly affect product selectivity and
stereoselectivity.
(a) Product Selectivity
Acetone is reduced at a lead cathode in an
acidic aqueous solution to give the
corresponding alcohol, isopropyl alcohol, while
the reduction with zinc and copper cathodes
provides the corresponding alkane, propane
[16].
