Atomic Imaging of Nanoparticle Catalysts during Operation

该项目是斯旺西大学纳米材料实验室（涵盖纳米尺度的物理、化学和工程）与Johnson Matthey技术中心（位于牛津附近Harwell的DIAMOND光源）通过其像差校正电子显微镜设施进行的合作。新型透射电子显微镜（TEM）可以在显微镜中心的细胞内进行化学反应过程中对单个纳米颗粒催化剂进行原子分辨率成像。原子结构和催化剂的化学选择性之间的相关性是发现绿色经济中新的、环境友好的纳米结构催化剂的核心。斯旺西集团在通过簇束方法生产尺寸选择和成分控制纳米颗粒方面的世界领先专业知识将被用于生产新型催化剂，并与JM在催化化学、先进成像和工业开发方面的经验相结合。这是一个令人兴奋和苛刻的项目，对一个优等生来说，具有很大的研究影响和职业发展前景。项目主管：Richard E Palmer教授（斯旺西），Manfred Schuster博士（庄信万丰）

Project descriptionThis project is a collaboration between the Nanomaterials Lab at Swansea University, which covers physics, chemistry and engineering on the nanometre-scale, and the Johnson Matthey Technology Centre through their aberration-corrected electron microscopy facility located at the DIAMOND Light Source at Harwell near Oxford. The new transmission electron microscope (TEM) enables atomic-resolution imaging of individual nanoparticle catalysts during the process of a chemical reaction inside a cell located in the heart of the microscope. The correlation between atomic structure and the chemical selectivity of the catalyst is central to the discovery of new, environmentally-friendly nanostructured catalysts for the green economy. The world-leading expertise of the Swansea group in the generation of size-selected and composition-controlled nanoparticles by cluster beam methods will be exploited to produce the new model catalysts, and coupled to JM's experience in catalytic chemistry, advanced imaging and industrial exploitation. This is an exciting and demanding project for a top student, with great prospects for research impact and career development.Project supervisors: Prof Richard E Palmer (Swansea), Dr Manfred Schuster (Johnson Matthey)
