Abstract
Herein, we designed a NiCo<sub>2</sub>S<sub>4</sub>@N/S–CeO<sub>2</sub> composite with amplified electrocatalytic oxygen reduction (OR) capability by the <italic>in situ</italic> growth of NiCo<sub>2</sub>S<sub>4</sub> nanoparticles on CeO<sub>2</sub> nanospheres with simultaneous doping of nitrogen and sulfur.
