Hierarchical Heterostructures of NiCo(2)O(4)@XMoO(4) (X = Ni, Co) as an Electrode Material for High-Performance Supercapacitors

Hierarchical heterostructures of NiCo(2)O(4)@XMoO(4) (X = Ni, Co) were developed as an electrode material for supercapacitor with improved pseudocapacitive performance. Within these hierarchical heterostructures, the mesoporous NiCo(2)O(4) nanosheet arrays directly grown on the Ni foam can not only...

description Hierarchical heterostructures of NiCo(2)O(4)@XMoO(4) (X = Ni, Co) were developed as an electrode material for supercapacitor with improved pseudocapacitive performance. Within these hierarchical heterostructures, the mesoporous NiCo(2)O(4) nanosheet arrays directly grown on the Ni foam can not only act as an excellent pseudocapacitive material but also serve as a hierarchical scaffold for growing NiMoO(4) or CoMoO(4) electroactive materials (nanosheets). The electrode made of NiCo(2)O(4)@NiMoO(4) presented a highest areal capacitance of 3.74 F/cm(2) at 2 mA/cm(2), which was much higher than the electrodes made of NiCo(2)O(4)@CoMoO(4) (2.452 F/cm(2)) and NiCo(2)O(4) (0.456 F/cm(2)), respectively. Meanwhile, the NiCo(2)O(4)@NiMoO(4) electrode exhibited good rate capability. It suggested the potential of the hierarchical heterostructures of NiCo(2)O(4)@CoMoO(4) as an electrode material in supercapacitors.
