Cobalt chromium vanadium layered triple hydroxides as an efficient oxygen electrocatalyst for alkaline seawater splitting

Abstract

Cobalt chromium vanadium layered triple hydroxides have been identified as a promising electrocatalyst for seawater splitting. The insertion of vanadium as a third metal into cobalt chromium layered double hydroxides not only adds extra cationic active sites but also facilitates electronic transition from Co(II) to V(V) boosting the OER activity and suppressing the CER.
