Towards an improved understanding of the surface chemistry and motion of adsorbates within zeolitic structures.

在与格拉斯哥大学的新合作中，约翰逊万丰正在赞助EPSRC工业案例博士学位。本研究旨在结合使用（i）反应测试、（ii）光谱学、（iii）电子显微镜和（iv）衍射技术来研究高表面积沸石中催化事件的基本方面。沸石结构和物理化学性质的影响将与吸附物/反应物的反应性相关。这将包括研究沸石的材料性质对催化剂框架内的反应性和扩散的影响。将探讨中间体和产物的形成与沸石结构之间的关系，其中原位红外光谱起着重要作用。还将在不同的时间尺度和长度尺度上研究反应期间沸石的结构变化。这将涉及使用合成或商业沸石和反应研究沿着，以及在ISIS设施（即非弹性和准弹性中子散射）和金刚石光源（即X射线吸收光谱、X射线衍射、透射电子显微镜和红外光谱）进行操作表征。学生将主要位于哈威尔研究中心，这是位于卢瑟福阿普尔顿实验室在牛津郡。此外，每年，学生将被要求在公司的英国研究中心之一实习。

In a new collaboration with the University of Glasgow, Johnson Matthey are sponsoring an EPSRC Industrial CASE Ph.D. studentship to use a combination of (i) reaction testing, (ii) spectroscopy, (iii) electron microscopy and (iv) diffraction techniques to investigate fundamental aspects of catalytic events in high surface area zeolites.The effect of zeolite structure and physico-chemical properties will be correlated with the reactivity of adsorbates/reactants. This will include studying the effect of material properties of zeolites on reactivity and diffusion within the catalyst framework. The relationship between the formation of intermediates and products with respect to zeolite structure will be explored, with in situ infrared spectroscopy playing a major role. Structural change in the zeolites during reaction will also be studied over different timescales and length scales. This will involve the use of synthesised or commercial zeolites and reaction studies along with operando characterisation at the ISIS Facility (i.e. inelastic and quasi-elastic neutron scattering) and the Diamond Light Source (i.e. X-ray absorption spectroscopy, X-ray diffraction, transmission electron microscopy and infrared spectroscopy). The student will be primarily located at the Harwell Research Complex, which is located at the Rutherford Appleton Laboratory in Oxfordshire. In addition, each year, the student will be expected to spend a placement at one of the Company's UK research centres.
