项目摘要

The solid/liquid interface plays a fundamental role in a diverse range of physical phenomena, for example in catalysis, crystal growth and in many biological reactions that govern the building of the human body and the functioning of the brain. Unravelling the atomic structure at the solid/liquid interface remains, therefore, one of the major challenges facing surface science today for it is only by understanding the physical processes in model systems that we can extrapolate to more complex environments. The key to developing this understanding lies in the preparation and study of model surfaces with well-defined elemental reaction sites.The development of alternative methods of energy supply and storage requires major advances in materials research. Such advances may now be achieved by the manipulation of molecular and atomic-scale processes, leading to an increased understanding of the physical and chemical properties of new materials. In particular, design of these materials may become possible from fundamental principles, i.e. understanding surface properties, as distinct from the bulk material properties, by the application of modern experimental techniques. The aims of this proposal are to further the understanding of the atomic and electronic structure at the electrochemical interface particularly to develop a fundamental understanding of the oxidation and reduction of transition metal multilayer films deposited by electrochemical methods. Due to the buried nature of the electrochemical interface, it is inaccessible to most standard surface science techniques that employ strongly adsorbed electron probes to gain surface sensitivity. Study of the interface is restricted to techniques that employ penetrating radiation, such as x-ray scattering or to imaging techniques such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM). The utilization of synchrotron radiation facilities (the European Synchrotron Radiation Facility in Grenoble and the Diamond Light Source at the Rutherford Appleton Laboratory) is a key component of this project. They offer state-of-the-art equipment for performing x-ray scattering experiments with high incident x-ray flux, energy tuneability and high resolution. Using such equipment it will be possible to probe surface atomic structure and the structures of adsorbed species with sub-monolayer resolution and also to gain electronic structure information from selected interface atoms that form the boundary between the solid surface and the liquid electrolyte where electric field driven reactions occur. By combining x-ray scattering (reciprocal space information) and imaging techniques (real space information) it will be possible to build a detailed picture of a surface structure under 'real' working conditions.
固体/液体界面在多种物理现象中起着重要作用,例如在催化、晶体生长和许多控制人体构造和大脑功能的生物反应中。因此,解开固体/液体界面的原子结构仍然是当今表面科学面临的主要挑战之一,因为只有通过理解模型系统中的物理过程,我们才能推断出更复杂的环境。发展这种理解的关键在于具有明确定义的元素反应位点的模型表面的制备和研究。能源供应和储存替代方法的发展需要在材料研究方面取得重大进展。这种进步现在可以通过操纵分子和原子尺度的过程来实现,从而增加对新材料的物理和化学性质的了解。特别是,这些材料的设计可以从基本原理,即理解表面性质,作为不同于块状材料性质,通过现代实验技术的应用成为可能。本建议的目的是进一步了解电化学界面上的原子和电子结构,特别是对电化学方法沉积的过渡金属多层膜的氧化和还原有一个基本的了解。由于电化学界面的埋藏性质,大多数标准的表面科学技术都无法使用强吸附电子探针来获得表面灵敏度。对界面的研究仅限于使用穿透辐射技术,如x射线散射或成像技术,如扫描隧道显微镜(STM)和原子力显微镜(AFM)。同步辐射设施(格勒诺布尔的欧洲同步辐射设施和卢瑟福阿普尔顿实验室的钻石光源)的利用是该项目的关键组成部分。他们提供最先进的设备进行高入射x射线通量,能量可调谐和高分辨率的x射线散射实验。使用这种设备,将有可能以亚单层分辨率探测表面原子结构和吸附物质的结构,也可以从形成固体表面和液体电解质之间边界的选定界面原子获得电子结构信息,电场驱动的反应发生在那里。通过结合x射线散射(互反空间信息)和成像技术(真实空间信息),将有可能在“真实”工作条件下建立表面结构的详细图像。
