Adv. Funct. Mater 以Ni （OH）2 /石墨烯和多孔石墨为电极的超级电容器？这是发表在Adv. Funct. Mater上，题目：Advanced Asymmetric Supercapacitors Based on Ni(OH) 2 /Graphene and Porous Graphene Electrodes with High Energy Density，主要讲述了以Ni （OH）2 / 石墨烯 和多孔 石墨 为超级电容器电极，以其独特的结构显示了非常好的电化学性能，具有非常高的能量密度和较高的循环寿命。本文引文61篇。In order to achieve high energy and power densities, a high-voltage asymmetric??supercapacitor is successfully fabricated using Ni(OH) 2 /graphene and porous graphene as the positive and negative electrodes, respectively. Because of their unique structure, both of these materials exhibit excellent electrochemical performances. The optimized asymmetric supercapacitor could be cycled reversibly in the high-voltage region of 0–1.6 V and displays intriguing performances with a maximum specifi c capacitance of 218.4 F g ? 1 and high energy density of 77.8 Wh kg ? 1 . Furthermore, the Ni(OH) 2 /graphene//porous graphene supercapacitor device exhibits an excellent long cycle life along with 94.3% specifi c capacitance retained after 3000 cycles.图片1.jpg查看更多0个回答 . 13人已关注
求助一个配位化学的问题？这个配体和Co配位，文献是这样的Potassium??hydride??(0.102??g,??2.54mmol),??(BrHBA-Et)H4（该配体）(0.292 g, 0.640), and 10 mL??of THF were combined??in a 20 mL??vial, and the resulting reaction mixture was stirred for 16 h.??CoCl2(0.083 g, 0.640 mmol) was then added and the dark green solution was stirred for 16 h. 我的 氯化 钴是蓝色的 无水 的，加入后并没有黑绿色而是深蓝色！什么原因？这个配合物能跟氧氧合但是作者并没有在无氧条件做，考虑可能因为室温反应不容易活化氧！QQ图片20141030120736.png查看更多5个回答 . 11人已关注
