中文摘要: |
本文分别利用非共轭桥和共轭桥将三联吡啶钌配合物固载到氧化石墨烯表面,制备了复合物Ru1-GO和Ru2-GO。采用红外吸收光谱、紫外-可见吸收光谱、X射线能量色散光谱、透射电镜及X-射线粉末衍射等多种方法对复合物进行了详细表征,并利用光电流响应测试对它们的光伏性能进行了比较。结果显示,含有共轭桥的复合物Ru2-GO产生的光电流强度可以达到3.5 μA/cm2,大约是复合物Ru1-GO的3.3倍,说明固载桥结构对钌配合物共价修饰的石墨烯纳米复合物的光伏性能有着重要的影响。 |
英文摘要: |
In this work graphene oxide was covalently modified by ruthenium trisbipyridine through non-conjugative and conjugative bridges respectively. The obtained ruthenium trisbipyridine-graphene oxide (Ru(II)-GO) nanocomposites were characterized by IR absorption spectroscopy, UV-vis absorption spectrum, energy dispersive X-ray spectrum, transmission electron microscope image and X-ray power diffraction in detail. Especially, their photovoltaic properties were detected by photocurrent response measurements. Under visible light irradiation, the Ru(II)-GO with conjugative bridge exhibited a large photocurrent density of 3.5 μA/cm2, which was 3.3 times as that of the Ru(II)-GO with non-conjugative bridge, indicating that the bridge structures have significant influence on the photovoltaic properties of Ru(II)-GO nanocomposites. |
