While Ni metal catalyzes the hydrogen evolution reaction (HER) exclusively under CO 2 RR conditions, Ni single atomic sites present a high CO selectivity of 95% under an overpotential of 550 mV in water, and an excellent stability over 20 hours’ continuous electrolysis. The current density can be scaled up to more than 50 mA cm?
