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

在与格拉斯哥大学的一项新合作中，Johnson Matthee赞助了EPSRC工业案例博士研究生，使用(I)反应测试、(Ii)光谱、(Iii)电子显微镜和(Iv)衍射技术的组合来研究高比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/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和扩散的影响。将探索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主要作用。还将在不同的时间尺度和长度尺度上研究沸石在反应过程中的结构变化。这将涉及使用合成或商业沸石和反应研究，以及在ISIS设施(即非弹性和准弹性中子散射)和钻石光源(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)上进行的操作数表征。这名学生将主要位于哈威尔研究中心，该中心位于牛津郡的卢瑟福·阿普尔顿实验室。此外，每年，学生将被期望在公司的英国研究中心之一进行安置。

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.
