Interaction Between Metals and Ionic Liquids

离子液体是一种不寻常的分子，它既是盐，又是室温下的液体。人们对离子液体的兴趣围绕着它们作为挥发性有机物的可持续绿色替代品以及其他高能过程的使用。虽然对它们的化学配方有一些限制，但估计存在10^6种选择。然而，人们对离子液体和金属之间的相互作用知之甚少，尽管有证据表明，用金属智能设计这些解决方案可以带来理想的性能和能力。两个例子是：1)金属颗粒的受控合成，有可能取代现有的高能工艺，以及2)用于电池应用。这个项目将寻求了解不同潜在的IL成分与金属固体和离子相互作用所产生的基础化学。这个项目将使用广泛的技术来测量金属水溶液的变化。这包括物理特性测量密度、粘度和表面张力。关键的化学性质，包括pH值和电导率也将被记录下来。为了探索化学形态，将使用核磁共振。综上所述，所有这些都将被用于同步加速器的应用，以进一步研究成键结构。最后，还将使用电化学技术来理解两者之间的关系。一个整体的方法，以及这一系列的技术，是获得一个完整的图景的唯一途径，使我们能够理解并因此为感兴趣的应用程序创建理想的组合。

Ionic liquids are unusual molecules, which are salts and simultaneously liquid at room temperature. The interest in ionic liquids is around their use as sustainable green replacements for volatile organics, as well as other high energy processes. Whilst there are some restrictions on their chemical formulation, it is estimated that 10^6 options exist. However, very little is understood about the interactions between ILs and metals, although there is evidence that intelligent design of these solutions with metals can lead to desirable properties and capabilities. Two examples are: 1) the controlled synthesis of metal particles, with the potential to replace existing high-energy processes, and 2) for use in battery applications. This project will seek to understand the underpinning chemistry resulting from the interaction of different potential IL constituents with metal solids and ions. This project will use a breadth of techniques to measure changes to the aqueous-IL-metal solutions. This includes physical property measurements density, viscosity, and surface tension. Key chemical properties including pH and conductivity will also be recorded. To probe the chemical speciation, the use of NMR will be employed. Taken together, all of this will be used to make synchrotron applications to further study the bonding structures. Finally, the use of electrochemical techniques to understand the relationship will also be employed. A holistic approach, with this range of techniques, is the only way to gain a complete picture allowing us to understand and therefore create ideal combinations for applications of interest.
