Prussian blue analogues (Ni₃[Fe(CN)₆]₂)) derived nanocube‐like Ni(OH)₂ was grown evenly on the surface of GO via solution‐precipitation and potassium hydroxide etching process at room temperature. Due to the even dispersion of Ni(OH)₂ nancubes, the obtained sample Ni(OH)₂/GO exhibits a maximum specific capacitance of 1299 F g⁻¹ at 0.5 A g⁻¹, excellent electrochemical stability (capacity retention of 63% from 0.5 A g⁻¹ to 10 A g⁻¹), and long‐cycle stability (capacity retention of 78% over 2000 cycles).

MOF衍生的Ni（OH）2纳米立方体/ GO用于高性能超级电容器

在室温下，通过溶液沉淀和氢氧化钾蚀刻工艺，在纳米颗粒表面均匀地生长了普鲁士蓝类似物（Ni ₃ [Fe（CN）₆ ] ₂）纳米立方体状的Ni（OH）₂。由于Ni（OH）₂纳米粒子的均匀分散，因此获得的样品Ni（OH）₂ / GO在0.5 A g ^{-1的条件下}具有1299 F g ^-1的最大比电容，优异的电化学稳定性（容量保持率达63％从0.5 A g ^-1到10 A g ^-1）和长周期稳定性（在2000个周期内容量保持率达78％）。
