Preparation of electrocatalysts mostly depends on the use of multiple initial materials – inorganic salts or organometallic precursors, nanostructured carbon, organic additives, and carbonization under modifying atmospheres (e.g. NH3) – with the examples of electrocatalysts arising from a single precursor being less common. By mixing metal and the catechol-imidazole units together, we get direct entry into a highly efficient bifunctional oxygen electrocatalyst, which alleviates the need for additional dopants and modifying conditions. We demonstrate that by fine-tuning the chemical nature of organic linkers and altering metal-organic combinations, one is able to modulate the electrochemical properties of a single precursor-derived electrocatalyst material.
