论文名称：9.Controlled Synthesis of Hierarchical NiO Hollow Spheres with Nanosheets for High Performance Supercapacitors

发表刊物：Journal of Chemistry Materials

摘要：In this work, we report a facile strategy for the controlled synthesis of nickel oxide (NiO) hollow spheres
(HSs) assembled from nanosheets (NSs). The Ni2CO3(OH)2 NSs are first grown on sulfonated
polystyrene (sPS) hollow spheres by a low-temperature solution route. NiO HSs with well preserved
morphology are then obtained by calcining the as-prepared sPS@ Ni2CO3(OH)2 NSs composite HSs.
Because of the hollow interior and hierarchical structure, these NiO nanosheet hollow spheres have
a relatively high specific surface area of 62 m2 g1. When evaluated for supercapacitive performance,
these hierarchical NiO HSs demonstrate improved electrochemical properties with a high capacitance
of 415 F g1 even at a high charge–discharge current rate of 3 A g1 and 91% of which can be retained
after 1000 charge–discharge cycles.
