It is highly desirable to design and develop earth-abundant electrocatalysts for efficient and durable oxygen evolution reaction (OER) under alkaline conditions. In this communication, we demonstrate the development of CaMoO4 nanosheet arrays on nickel foam (CaMoO4/NF) as a durable high-performance non-noble-metal electrocatalyst for the OER. CaMoO4/NF shows high catalytic activity and needs an overpotential of only 345 mV to attain a geometrical catalytic current density of 50 mA cm−2 in 1.0 M KOH. Notably, it also shows high long-term electrochemical durability for at least 25 h.
