Design of NiO Flakes@CoMoO₄ Nanosheets Core-Shell Architecture on Ni Foam for High-Performance Supercapacitors.

ABSTRACT: As typical electrode materials for supercapacitors, low specific capacitance and insufficient cycling stability of transition metal oxides (TMOs) are still the problems that need to be solved. Design of core-shell structure is considered as an effective method for preparation of high-performance electrode materials. In this work, NiO flakes@CoMoO₄ nanosheets/Ni foam (NiO flakes@CoMoO₄ NSs/NF) core-shell architecture was constructed by a two-step hydrothermal method. Interestingly, the CoMoO₄ NSs are vertically grown on the surface of NiO flakes, forming a two-dimensional (2D) branched core-shell structure. The porous core-shell architecture has relatively high surface area, effective ions channels, and abundant redox sites, resulting in excellent electroche
