In article number 1700238, Jianhua Sun, Xiaopeng Li, and co‐workers, report a hollow cobalt and nitrogen co‐doped carbon nanopolyhedra catalyst derived from a MOF that effectively traps O2 molecules available in the electrolyte. The hollow structure enables significant improvement in oxygen reduction reaction kinetics and stability. New insights into the spatial confinement effect and new guidelines...
A novel strategy for the fabrication of hollow Co and N‐codoped carbon nanopolyhedra (H‐CoNC) from metal–organic framework (MOF) using in situ evaporation of ZnO nanosphere templates is proposed. The excess Zn supply during the pyrolysis process is found beneficial in terms of high nitrogen (≈9.75 at%), relatively homogenous CoN bonding, and the electrochemically accessible hierarchical porous system...
