Representative work: The development of highly active and stable non-noble-metal electrocatalysts for water splitting is the main title toward energy conversion systems. CoFe2O4 has been reported as a promising oxygen evolution reaction (OER) electrocatalyst. However, CoFe2O4 showed poor conductivity and sluggish electrocatalysis in the hydrogen evolution reaction (HER). In this work a new hybrid catalyst was synthesized based on single-walled carbon nanotube (SWNT)-wrapped CoFe2O4 nanorods. The synergistic effect between CoFe2O4 nanorods and SWNTs can not only increase the oxygen vacancies and optimize the electronic structure of the composite but also facilitate the adsorption and stabilization of hydroxyl, wh Developing efficient and durable multifunctional electrocatalysts for oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR) is of significant importance for many electrochemical energy devices, such as water electrolyzers, metal–air batteries, and fuel cells. Herein, the Rh–Cu alloy nanocrystals (NCs) are prepared with a simple wet-chemical approach. The tuning of morphology and the asymmetric electron distribution provide more efficient Rh–Cu bimetallic sites. Meanwhile, the incorporation of Cu into the Rh lattice could reduce the oxidation of Rh–Cu bimetallic sites and increase the catalytic stability. Under the tuning of the composition, t
