Electrocatalytic Hydrogenation of Olefins Using Palladium Metal Microparticles Deposited on Viologen Film-coated Graphite Felt

Abstract

Palladium (Pd) metal microparticles were deposited in a viologen-containing polymer layer on the surface of a graphite felt electrode. The Pd-deposited electrode is effective for the electrocatalytic hydrogenation of the carbon-carbon double bond part of alkyl olefins (1-hexene, 1-decene, cis-2-penetene), conjugated enones (2-cyclohexene-1-one, 4-isopropyl-2-cyclohexene-1-one, 3,5,5-trimetyl-2-cyclohexene-1-one), styrene, and trans-stilbene with 100% selectivity.
