ABSTRACT=<p>Self-supporting electrodes usually show excellent electrocatalytic performance which does not require coating steps, additional polymer binders, and conductive additives. Rapid <italic>in situ</italic> growth of highly active ingredient on self-supporting electric conductors is identified as a straight forward path to prepare binder-free and integrated electrodes. Here, Pd-doped Co<sub>3</sub>O<sub>4</sub> loaded on carbon nanofiber materials through electrospinning and heat treatment was efficiently synthesized, and used as a free-standing electrode. Benefiting from its abundant active sites, high surface area and effective ionic conduction capability from three-dimensional (3D) nanofiber framework, Pd-Co<sub>3</sub>O<sub>4</sub>@CNF works as bifunctional oxygen electrode and exhibits superior activity and stability superior to commercial catalysts.</p>
