室温离子液体是一类完全由阴、阳离子组成的物质,且在室温或室温附近呈现液态。与传统电解质溶液相比,它具有电化学窗口宽、蒸汽压低、沸点高以及电导率良好等优势,目前已在电化学等诸多领域有广泛的应用。离子液体具有迥异于水溶液体系和有机溶剂体系的特点,因而“电极/离子液体”界面结构与“电极/水溶液”界面结构截然不同。近年来的研究结果表明,离子液体在电极表明会自发形成多层阴、阳离子相间的层状结构,且表现出对电位的依赖性。但目前对这种层状结构的研究还停留在单种离子液体与电极间的相互作用,但离子液体具有可设计性且种类繁多,其本身的组成结构对离子液体层状结构影响的系统研究尚未被报道。另外,在离子液体中加入氧化还...Ionic liquids (ILs) are a kind of substance, entirely composed of ionic species and presented as liquid at and near room temperature. Compared with traditional electrolyte solutions, ILs have many important features, such as wide electrochemical window, low vapor pressure, high boiling point and good electrical conductivity, it have been widely used in various fields. The structure of the electric...学位:理学硕士院系专业:化学化工学院_物理化学学号:2052014115156
