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)

项目描述该项目是斯旺西大学纳米材料实验室与庄信万丰技术中心之间的合作，该实验室涵盖纳米尺度的物理、化学和工程，通过其位于牛津附近哈韦尔钻石光源的像差校正电子显微镜设施。新型透射电子显微镜 (TEM) 能够在位于显微镜中心的细胞内的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。催化剂的原子结构和化学选择性之间的相关性对于发现用于绿色经济的新型环保纳米结构催化剂至关重要。斯旺西集团在通过簇束方法生成尺寸选择和成分控制纳米粒子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。对于顶尖学生来说，这是一个令人兴奋且要求很高的项目，在研究影响和职业发展方面具有广阔的前景。项目导师：Richard E Palmer 教授（斯旺西）、Manfred Schuster 博士（庄信万丰）
