Selective nitrogen-doping of graphene oxide with a high pyridinic N ratio (51%; L-GO) was achieved by laser irradiation of graphene oxide with ammonia. The resulting L-GO exhibited enhanced electrocatalytic properties; specifically, the overpotential of the hydrogen evolution reaction (HER) was improved by over 400 mV at 10 mA cm-2 compared to the pristine graphene oxide.
