Abstract

A space-confined strategy has been used to control the pyrolysis of two-dimensional (2D) NiCo-MOF@ZIF-L(Zn). A thin SiO₂ layer as a confined space could avoid the destruction of the 2D morphology during pyrolysis and expose more active sites. The obtained NiCo–NC material exhibits high ORR and Zn–air battery performance.
