Defective graphene as metal free catalyst for chemoselective olefin hydrogenation by hydrazine

Abstract

A series of defective graphenes containing or not N, B, S and other heteroatoms exhibit general activity as metal-free catalysts for the hydrogenation of C=C double bonds by hydrazine in the presence of oxygen. The best performing graphene was the one obtained from pyrolysis of alginate and subsequent exfoliation by sonication. The material was reusable in three consecutive runs without decay in its catalytic activity and it exhibits 99 % chemoselectivity for C=C double bond vs. nitro group hydrogenation in contrast with conventional Pd supported on carbon that is almost unselective. Theoretical calculations using a model for defective graphene for styrene hydrogenation show adsorption of substrate by π-π stacking resulting in activation of the double bond and a direct interaction of cis-diimide with the C=C group.
