Fe (Oxy)hydroxide Oxygen Evolution Reaction Electrocatalysis: Intrinsic Activity and the Roles of Electrical Conductivity, Substrate, and Dissolution

Autor: Matthew G. Kast, Nemanja Danilovic, Jie Fan, Shannon W. Boettcher, Michaela S. Burke, Shihui Zou

Publikováno v: Chemistry of Materials. 27:8011-8020

Fe cations dramatically enhance oxygen evolution reaction (OER) activity when incorporated substitutionally into Ni or Co (oxy)hydroxides, serving as possible OER active sites. Pure Fe (oxy)hydroxides, however, are typically thought to be poor OER ca
