摘要
High electroactivity and good mechanical robustness of electrode materials are essential to deliver excellent elec-trochemical energy storage performance.Herein,metal–organic frameworks(MOF)derived mixed metal oxides(MMO,ZnO@NiO and Co_(3)O_(4)@NiO)are prepared by a two-step annealing process in air.Zinc-based MOF(ZIF-8)and cobalt-based MOF(ZIF-67)were employed,respec-tively,as hard templates for the chemical encapsulation of Ni(OH)_(2)nanostructures by hydrothermal synthesis.
