A research team led by Prof. Yan Wensheng from the University of Science and Technology of China (USTC) has created the innovative "Janus" dual-atom catalyst (FeCo-N3O3@C) with Fe and Co atoms coordinated synergistically through an N-O bridge, which has showed exceptional performance in both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The study was published in Nature Synthesis.
