以水和甘油为混合溶剂，采用水热法合成了由纳米片结构单元组装而成的β-Ni（OH）2康乃馨状结构。通过将合成的康乃馨状β-Ni（OH）2在空气中于400 °C热分解2 h，得到了由具有纳米孔的纳米片组装而成的NiO康乃馨。合成的β-Ni（OH）2具有不同于β-Ni（OH）2纳米片的循环伏安曲线。
β-Ni(OH)2 carnationlike structures assembled from nanosheet building blocks were successfully synthesized via a hydrothermal method through the hydrolysis of nickel acetate in mixed solvents of water and glycerol. NiO carnations assembled from nanosheets with nanopores were obtained by thermal decomposition of the as-synthesized carnationlike β-Ni(OH)2 at 400 °C for 2 h in air. The as-obtained β-Ni(OH)2 carnations showed a different cyclic voltammogram (CV) curve from that of β-Ni(OH)2 nanosheets.
