Abstract
An amorphous Co-doped MoS2 coated highly crystalline pyrite-phase CoS2 hierarchical nanoarray exhibits ultrahigh activity towards acidic hydrogen evolution with a low onset potential (∼44 mV) and a small overpotential of ∼110.5 mV for driving the current density of ∼10 mA cm−2, ascribed to its novel hierarchical structure and the Co doping caused synergistic effects.
