Hydrogen production through electrochemical process is at the heart of key renewable energy
technologies including water splitting and hydrogen fuel cells. Despite tremendous efforts,
exploring cheap, efficient and durable electrocatalysts for hydrogen evolution still remains as
a great challenge. Here we synthesize a nickel–carbon-based catalyst, from carbonization of
metal-organic frameworks, to replace currently best-known platinum-based materials for
electrocatalytic hydrogen evolution. This nickel-carbon-based catalyst can be activated to
obtain isolated nickel atoms on the graphitic carbon support when applying ...

Here we synthesize a nickel–carbon-based catalyst, from carbonization of metal-organic frameworks, to replace currently best-known platinum-based materials for electrocatalytic hydrogen evolution. This nickel-carbon-based catalyst can be activated to obtain isolated nickel atoms on the graphitic carbon support when applying electrochemical potential, exhibiting highly efficient hydrogen evolution performance with high exchange current density of 1.2mAcm 2 and impressive durability. This work may enable new opportunities for designing and tuning properties of electrocatalysts at atomic scale for largescale water electrolysis.
