Synergistic Effect of Cobalt/Ferrocene as a Catalyst for the Oxygen Evolution Reaction

There is a great deal of interest in the development of electrocatalysts for the oxygen evolution reaction (OER) that are stable and have high activity because this anodic half-reaction is the main bottleneck in water splitting and other key technologies. Cobalt and iron oxide and oxyhydroxide elect...

Cobalt and iron oxide and oxyhydroxide electrocatalysts constitute a cheaper alternative to the highly active and commonly used Ir- and Ru-based catalysts. Most of the described electrocatalysts require tedious synthetic and expensive preparation procedures. We report here a facile and straightforward preparation of an electrocatalyst by a combination of commercial compounds, such as cobalt chloride and ferrocene. A highly active and stable OER electrocatalyst is obtained, which shows a low overpotential in the alkaline medium as a consequence of a synergistic effect between both compounds and is inexpensive. © 2024 American Chemical Society.This work has been supported by public funds: J.M.A. and A.L.D.L. acknowledge Grant PID2021-124160B-I00/ AEI/10.13039/501100011033/FEDER, UE; M.P. acknowledges Grant TED2021-129694B-C22 funded by MCIN/AEI/10.13039/501100011033 and by the European Union Next Generation EU/PRTR; and M.V.M.H. acknowledges the CEOTRES-CM project funded by the Comunidad de Madrid with Grant Number Y2020/EMT-6419.
