摘要
本文利用石墨烯分散液和钌配合物[Ru(Py_2G_1MeBip)(XPOH)](PF_6)_2在ITO基底上组装出石墨烯修饰的钌配合物电极以及钌配合物修饰的石墨烯电极,分别记为Ru/G和G/Ru。电极表面的接触角分析证明可在电极表面按照需求组装Ru分子膜和石墨烯膜,且说明了实验中芘基的疏水性高于石墨烯。循环伏安实验证明Ru/G电极和G/Ru电极表现出可逆的氧化还原过程,在0.4~0.6V之间出现Ru(II/III)的氧化还原峰。紫外可见吸收光谱表明用石墨烯对钌单分子膜进行修饰有利于复合膜对光的吸收。以上分析结果表明采用石墨烯对单分子膜进行修饰,可提高电极的光电特性,将其应用于光伏领域具有潜在开发价值。
Graphene dispersion and [Ru(Py_2G_1MeBip)(XPOH)](PF_6)_2 were utilized for the preparation of Graphene electrode on the ITO base,which were named Ru/G and G/Ru.The analyses of the electrode surface contact angle shows that the Ru monolayer film and Graphene film can be well assembled as required,which can also proved the hydrophobic of Py group is better than Graphene.Ru/G and G/Ru composite membranes were also prepared by molecular film self-assembly with the graphene films and Ru complex by different ways,which were characterized by monitoring CV and UV-Vis measurements.The findings strongly supported the feasibility of the modified behavior of Graphene on the Monolayer film,which present well strength photoelectric properties.
