英文摘要	通过ZnO模板辅助电沉积法制备了中空网状笼还原氧化石墨烯，具有纳米管、多孔结构、网状结构和3D微米中空笼等多层次架构. 这样的结构能够同时促进电化学活性物种的传输，提高电极材料的利用率，以及提升超级电容器性能. 该类中空网状笼还原氧化石墨烯做超级充电器电极材料时表现出了优良的电化学性能，研究结果显示，在1.0 A•g-1时比电容达到393 F•g-1. 而且当电流密度从1.0 A•g-1增加到20 A•g-1，电容仅衰减了21.2%，10000周循环后比电容损失小于1%，表明具有优异的电容稳定性.; The reduced graphese oxide (RGO) hollow network cages were synthesized via zinc oxide (ZnO) template-assisted electrodeposition. The as-prepared RGO hollow network cages exhibited the multi-level architectures, from nano sheets, porous structures, networks, to 3D microscaled hollow cages, which can simultaneously optimize transport of electroactive species, utilization rate of electrode material, and super capacitive performance. Electrochemical measurements confirmed the superior performance of RGO hollow network cages for supercapacitors (SCs), such as high Csp (393 F•g-1 at 1.0 A•g-11), excellent rate capability (21.2% Csp loss from 1.0 to 20 A•g-1), and superior cycling stability (< 1% Csp loss after 10000 cycles).; This work was supported by National Natural Science Foundation of China (No. 51173212), National Basic Research Program of China (No. 2015CB932304), Natural Science Foundation of Guangdong Province (Nos.
