Summary: By combining architectural design with defect engineering, defect-rich yolk-shell hollow spheres of ultrafine NiCo2S4-x nanoparticles as sulfur hosts were prepared using an anion-exchange method. The design of sulfur defects endows the hollow spheres with enhanced electronic conductivity and affinity for polysulfides, while the yolk-shell structure provides large cavities for increased sulfur storage and relief of electrode volume expansion during cycling. As a result, the NiCo2S4-x-hosted sulfur cathode showed enhanced cycling stability with a negligible capacity fading rate of 0.0754% per cycle after 500 cycles at 1 C, and achieved an outstanding rate capability of 628.9 mAh g(-1) up to 5 C.

Summary: Direct observation of catalytic roles of surface defects and their in situ restructuring through storing catalytic trajectories and collectively presenting reactivity profiles on solid surfaces using in situ transmission electron microscopy reveals promising catalytic surface defects with a fine balance between reactivity and stability. DFT calculations result in a novel rhombohedral Volcano-type Zebra-crossing plot for the structure-activity relation regarding the improved reactivity by strained defect sites, different from a conventional Volcano-type plot in catalysis studies. The current in situ method is expected to assist the design and synthesis of more nanocatalysts in the future.
