【摘要】 在水热条件下一步自组装合成系列同构X-MOF（X₆O（TATB）₄（H⁺）₂·（H₂O）₈·（DMF）₂,X=Zn、Co、Ni;H₃TATB=4,4’,4″-s-triazine-2,4,6-triyl-tribenzoic acid;DMF=N,N-二甲基甲酰胺）和氧化石墨烯（GO）的复合材料（X-MOF@GO）,并探究其作为超级电容器电极材料的电化学性能。通过X射线粉末衍射、X射线光电子能谱和扫描电子显微镜测试证明GO和MOFs复合成功。其中,性能最优的Ni-MOFs@1.5GO（GO的添加量为1.5 mL）的比电容高达694.8 F·g^-1(0.5 A·g^-1),约是Ni-MOF的2倍。电化学测试结果表明:复合材料X-MOF@1.0GO较其原MOF表现出更大的比电容和更好的倍率性能。在3.5 A·g^-1的电流密度下,1 000次循环充放电后,Ni-MOFs@1.0GO仍保持初始比电容量的81.2%。与活性炭（AC）组装的非对称超级电容器Ni-MOF@1.5GO//AC的性能最优,其功率密度为754.3 W·kg^-1时,能量密度为15.4 Wh·kg^-1,且循环3 000次后比电容保持率约为70.0%,显示出较长的循环寿命。更多还原

【Abstract】 A series of X-MOF@GO composited with X-MOF（X₆O（TATB）₄（H⁺）₂·（H₂O）₈·（DMF）₂, X=Zn, Co, Ni;H₃ TATB=4,4’,4″-s-triazine-2,4,6-triyl-tribenzoic acid; DMF=N,N-dimethylformamide） and graphene oxide（GO） as supercapacitor electrode materials were synthesized by one-step self-assembly under hydrothermal conditions.X-ray powder diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy showed that X-MOF@GO composites were successfully synthesized. Ni-MOF@1.5GO electrode with the best performance delivered a specific capacitance of 694.8 F·g^-1 at 0.5 A·g^-1. Moreover, the specific capacitance of Ni-MOF@1.5GO electrode was nearly twice of Ni-MOF, while the capacitance of Ni-MOFs@1.0 GO retained about 81.2% after 1 000 cycles indicating that GO doped Ni-MOF can boost the performance of MOFs materials effectively. A symmetrical capacitor based on Ni-MOF@1.5GO//AC（AC=activated carbon） electrode exhibited a high energy density of 754.3 W·kg^-1 at power density of 15.4 Wh·kg^-1, while the capacitance retention reached about 70.0% after 3 000 cycles.更多还原
