Tailoring the Compositions and Nanostructures of Trimetallic Prussian Blue Analog-Derived Carbides for Water Oxidation.

ABSTRACT: The electrochemical splitting of water for hydrogen production faces a major challenge due to its anodic oxygen evolution reaction (OER), necessitating research on the rational design and facile synthesis of OER catalysts to enhance catalytic activity and stability. This study proposes a ligand-induced MOF-on-MOF approach to fabricate various trimetallic MnFeCo-based Prussian blue analog (PBA) nanostructures. The addition of [Fe(CN)₆]^3- transforms them from cuboids with protruding corners (MnFeCoPBA-I) to core-shell configurations (MnFeCoPBA-II), and finally to hollow structures (MnFeCoPBA-III). After pyrolysis at 800 °C, they are converted into corresponding PBA-derived carbon nanomaterials, featuring uniformly dispersed Mn₂Co₂C nanoparticles. A
