Based on the thermal decomposition and phase transition at elevated temperature, the Cu4(SO4)(OH)6 precursor synthesized by a hydrothermal method could be converted into 3D nanoporous CuO. The nanoporous CuO retained the bamboo leaf-like shape and was composed of nanocrysals with grain size of 50 - 80 nm. The CuO electrode was very stable and exhibited a specific capacitance of 269.6 F g-1 at a current density of 0.25 A g-1. The CuO electrode could be cycled at least 500 cycles, and the capacitance retention ratio was as 88.79% at the current density of 2 A g-1.

纳米多孔竹叶状CuO的特性和超电容性能

基于高温下的热分解和相变,将水热法合成的Cu 4(SO 4)(OH)6前体转化为3D纳米多孔CuO。纳米多孔CuO保留了竹叶状形状,由粒径为50-80 nm的纳米晶体组成。CuO电极非常稳定,在0.25 A g -1的电流密度下具有269.6 F g -1的比电容。该CuO电极可以循环至少500个循环,并且在2 A g -1的电流密度下电容保持率为88.79%。
