For the goal of practical industrial development of fuel cells, design and synthesis of electrocatalysts for oxygen reduction reactions (ORR) with sustainable and high performance are of great significance. In this work, the coordination of NH 2 ‐carbon quantum dots (NCQDs) with Co 2+ on carbon black was reasonably achieved via one‐pot and low‐cost hydrothermal treatment for the first time. Citric acid (CA) and urea (UA) were taken as carbon and nitrogen sources for NCQDs, respectively. The coordination of Co 2+ and NCQDs were well‐characterized using spectroscopic techniques such as FTIR, UV‐visible absorption and fluorescence. Carbonization of carbon black‐supported Co/NCQDs at 800 °C under N 2 atmosphere endows the pyrolysis products with high catalytic activity. The Co−CoO X /Co−N−C possesses enhanced ORR performance in terms of positive onset‐potential (∼‐0.079 V vs. SCE) and half wave potential (E 1/2 ) (∼‐0.201 V vs. SCE), high stability, as well as the accelerated reaction kinetics. |
