摘要：

Mesoporous CoNiO2 (CNO) hexagonal nanoparticles are prepared via a hydrothermal microwave carbon bath process. The nanostructure and morphology of CNO NPs prepared at different hydrothermal temperatures are systematically studied and characterized. At the hydrothermal temperature of 140 1C, CNO hexagonal nanoparticles have a porous structure and a specific surface area of 53.56 m(2) g(-1). In addition, the as-prepared CNO electrode material exhibits a large capacitance of 801.00 F g(-1) at a current density of 0.5 A g(-1). The assembled CNO asymmetric supercapacitor shows a high energy density of 10.34 W h kg(-1) at the power density of 300 W kg(-1), which shows great potential as a novel electrode material in energy storage applications.
