A hierarchical CoTe2–MnTe2 hybrid nanowire array enables high activity for oxygen evolution reactions†
Abstract
In this communication, we demonstrate the development of hierarchical CoTe2–MnTe2 hybrid nanowires grown on Ti mesh (CoTe2–MnTe2/TM) as an electrocatalyst for the oxygen evolution reaction. The catalyst exhibits excellent conductivity and exposes sufficient active sites derived from its favorable composition and structure, which only needs an overpotential of 310 mV to drive a current density of 50 mA cm−2 in 1.0 M KOH.
