Tethering Mesoporous Pd Nanoparticles to Reduced Graphene Oxide Sheets Forms Highly Efficient Electrooxidation Catalysts

Abstract

Uniformly-sized mesoporous palladium (Pd) nanoparticles supported on reduced graphene oxide (rGO) surfaces can be prepared by solution phase synthesis. The rGO is modified with a block copolymer and a cationic surfactant was employed to assist the formation of mesoporous metal nanoparticle on the surface of the rGO. This process results in good electronic contact in the Pd-rGO hybrid material to assist in electrocatalysis. The mesoporous Pd nanoparticles tethered to rGO were employed in the electrooxidation of formic acid. These hybrid composite materials exhibited excellent stability, enhanced specific activity and mass activity compared to state-of-the-art Pd/C catalysts as well as other similar structures reported in the literature.
