High activity bifunctional non-noble electrocatalysts, targeting both ORR and OER, are rationally designed by integrating the merits of both NiFe2O4 quantum dots and carbons nanotubes (CNTs) (NiFe2O4(QDs)/CNTs), which possesses large specific surface area (584 m2 g−1), abundant NiFe2O4 quantum dots...
