An Fe(TCNQ)2 nanowire array on Fe foil: an efficient non-noble-metal catalyst for the oxygen evolution reaction in alkaline media

Author affiliations

Abstract

It is highly desirable to develop efficient and durable oxygen evolution reaction (OER) electrocatalysts. Herein, we report the in situ development of an Fe-(tetracyanoquinodimethane)2 nanowire array on Fe foil (Fe(TCNQ)2/Fe) via a solution immersion method. As a non-noble-metal OER electrocatalyst, such Fe(TCNQ)2/Fe needs an overpotential of only 340 mV to drive a geometrical catalytic current density of 10 mA cm−2 in 1.0 M KOH. Notably, it also shows strong long-term electrochemical durability capable of maintaining its catalytic activity for at least 110 h.
