Formatted abstract
Oxygen evolution reaction has attracted extensive attention in energy conversion and storage t echnology(e. g. water splitting and rechargeable metal–air batteries). Its sluggish kinetics demands effective electrocatalysts tominimize the reaction barrier. Transition metal (oxy)hydroxides with a layered structure are one of the most activenon-noble electrocatalysts. In this study, we compared the oxygen evolution performance of α-Co(OH)2, β-Co(OH)2and β-CoOOH. Our results showed that α-type hydroxide is more active than β-type with 60 mV lower overpotentialat 10 mA/cm2and three times higher current density at 450 mV overpotential. The plausible reason of this superioroxygen evolution activity is likely relevant to the large interlayer space in α-type hydroxide.
