Multiscale imaging for the investigation of catalysts and zeolites

作为英国催化中心团队的一员，这一奖学金提供了接触英国顶尖学者和哈威尔校区先进的X射线和中子表征技术的机会。此外，学生将与工业合作伙伴约翰逊·马泰密切合作，从而深入了解学术和工业研究环境。该项目将广泛利用戴蒙德新建的物理科学像差校正瞬变电子显微镜设施(EPSIC)和I14纳米探测器光束线设施。这些都是强大的技术，能够在催化中重要的一系列长度范围内的工作条件下研究材料。例如，孔坍塌或颗粒聚集发生在微米尺度上，而活性中心分布可能在纳米尺度上。通过利用纳米分辨原位显微镜(TEM)和50 nm分辨率I14光束线的X射线能力观察到的不同长度尺度，可以在相关工作条件下的一系列长度尺度上直观地了解催化剂的活性或失活过程。

By being a member of the UK Catalysis Hub team this studentship offers exposure to leading UK academics and the advanced X-ray and Neutron characterisation techniques available on the Harwell campus. In addition, the student will work closely with the industrial partners, Johnson Matthey, therefore gaining insight into both academic and industrial research environments. The project will make extensive use of the newly built physical sciences aberration corrected TEM facility (ePSIC) and I14 nanoprobe beamline facility at Diamond. These are powerful techniques able to study materials under working conditions over a range of length scales important in catalysis. For instance, pore collapse or particle agglomeration occur in the micrometer scale, whereas active site distribution may be on the nm scale. By exploiting the different length scales viewed by both the nm resolved in situ microscopy (TEM) and the X-ray capabilities of the 50 nm resolution I14 beamline, a thorough understanding of catalyst activity or deactivation processes can be visualised over a range of length scales under relevant working conditions.
