Fe₄S₄ Cubane Type Cluster Immobilized on a Graphene Support: A High Performance H₂ Evolution Catalysis in Acidic Water.

ABSTRACT: The development of alternate catalysts that utilize non-precious metal based electrode materials such as the first row transition metal complexes is an important goal for economic fuel cell design. In this direction, a new Fe₄S₄ cubane type cluster, [PPh₄]₂[Fe₄S₄(DMET)₄] (1) (DMET = cis-1,2-dicarbomethoxyethylene dithiolate) and its composite with functionalized graphene, (1@graphene) have been synthesized and characterized. The presence of nanocrystalline structures on graphene matrix in TEM and SEM images of 1@graphene indicate that the cluster (1) has been immobilized. The composite, 1@graphene evolves H₂ gas from p-toluene sulfonic acid (TsOH) in a mixture of H₂O and CH₃CN unde
