DNA-directed growth of ultrafine CoAuPd nanoparticles on graphene as efficient catalysts for formic acid dehydrogenation

Ultrafine and well dispersed CoAuPd nanoparticles grown on a DNA–reduced-graphene-oxide (DNA–rGO) composite have been successfully synthesized using a DNA-directed method. The resultant CoAuPd/DNA–rGO composite exhibits high activity and 100% H2 selectivity toward the dehydrogenation of formic acid without any additive at 298 K.
