Abstract
Oxygen evolution reaction (OER) is a core reaction of electrochemical water splitting accountable for converting electricity into an ideal energy carrier, “hydrogen.” This anodic reaction is kinetically sluggish due to multi-intermediates and the complex proton-coupled electron transfer process. The electrocatalyst with optimum surface and electronic structure reduces the kinetic energy barrier for challenging OER. Cobalt-based nanosheets have recently been recognized as highly efficient materials for OER due to their intrinsically active sites, rapid charge and mass transport, and fast reaction kinetics. This review summarizes the recent progress in cobaltbased nanosheets (oxide/hydroxide, boride, nitride, phosphide, and sulfide) for OER. The established mechanisms, structure design for high-output OER, and performance analysis of different Co-based nanosheets are discussed to promote the rational design of a highly efficient and cost-effective OER electrocatalyst.
