Research topics from publications: Hierarchical structures composed of MnCo2O4@MnO2 core–shell nanowire arrays with enhanced supercapacitor properties; Ultrathin porous nickel–cobalt hydroxide nanosheets for high-performance supercapacitor electrodes; Anion-exchange reaction synthesized CoNi2S4 nanowires for superior electrochemical performances. Representative work: In this paper, hierarchical MnCo2O4@MnO2 core-shell nanowire arrays (MnCo2O4@MnO2 NWAs) with mesoporous and large surface area are synthesized on 3D nickel foam via a facile, two-step hydrothermal approach without any adscititious surfactant and binder. The electrode architecture takes advantage of the synergistic effects contributed from both the porous MnCo2O4 nanowire core and the MnO2 shell layer. The fabricated MnCo2O4@MnO2 NWA electrode for supercapacitors in aqueous electrolyte exhibits a significantly enhanced specific capacitance (858 F g(-1) at 1 A g(-1)), high energy density (36.0 Wh kg(-1) at 252 W kg(-1)) and long-life cycling stability (retaining 88% of the initial capacitance Ultrathin porous nickel–cobalt layered double hydroxide (Ni–Co LDH) hybrid nanosheets on metal nickel sheets shows highly electrochemical performance which synthesizing via a facile hydrothermal method without any adscititious surfactant
