Atomic Imaging of Nanoparticle Catalysts during Operation

项目简介该项目是斯旺西大学纳米材料实验室与约翰逊万丰技术中心的合作，该实验室涵盖了纳米尺度的物理、化学和工程，通过位于牛津附近哈维尔的DIAMOND光源的像差校正电子显微镜设施。新的透射电子显微镜（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。原子结构和催化剂的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境友好纳米结构催化剂至关重要。斯旺西集团在通过簇束方法产生尺寸选择和成分控制纳米颗粒方面的世界领先的专业知识将被用于生产新的模型催化剂，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要求高的项目，为优秀的学生，研究影响和职业发展的巨大前景。项目主管：理查德E帕尔默教授（斯旺西），曼弗雷德舒斯特博士（约翰逊万丰）

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)
