Abstract

original image

Deoxyribonucleic acid (DNA) is used to functionalize graphene and to further guide the growth of ultrasmall palladium (Pd) nanocrystals with uniform distribution on graphene (Pd-DNA@Graphene), demonstrating greatly improved electrocatalytic performance towards formic acid oxidation for direct formic acid fuel cells.
