摘要：

Layered double hydroxides (LDHs) are prospective cathode materials for supercapacitors because of their outstanding theoretical specific capacitance and unique layered structure. However, the finite electroactive sites and cation species confine their practical application in supercapacitors. In this work, a hollow polyhedral ternary metallic Ni2CoMn1-LDH is prepared using zeolitic imidazolate framework-67 (ZIF-67) as the template. It has been found that the hollow dodecahedral structure constructed by thin nanosheets endows the Ni2CoMn1-LDH sa...
