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IR、UV-Vis、EDS、TEM及XRD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3.5μA/cm~2,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。
In this paper, ternary pyridine complexes were immobilized on the surface of graphene oxide by using non-conjugate and conjugate bridges, respectively. The complexes Ru1-GO and Ru2-GO were prepared. The composites were characterized by IR, UV-Vis, EDS, TEM and XRD. Their photocatalytic performance was compared by photocurrent response test. The results show that the photocurrent intensity of the Ru2-GO complex containing conjugated bridge can reach 3.5μA / cm ~ 2, which is about 3.3 times that of the complex Ru1-GO, indicating that the immobilization bridge structure covalently modified the ruthenium complex Of the graphene nanocomposite photovoltaic properties have a significant impact.
