The project will look at long term structural changes in heterogeneous catalysts and battery materials. We envisage performing long duration experiments using synchrotron techniques such as the capabilities of the I11 XRD beamline at the Diamond Light Source. Many catalyst materials undergo thermal cycling events during use which may lead to varied changes in structure and therefore performance, such as changes to the pore systems or active metal nanoparticle size. By monitoring these changes over long time scales, whilst maintaining reaction or temperature conditions will lead to an enhanced understanding of the processes involved and so could lead to improved catalyst design.

该项目将着眼于非均相催化剂和电池材料的长期结构变化。我们设想使用同步加速器技术进行长时间实验，例如在钻石光源处使用I11 XRD光束线的能力。许多催化剂材料在使用过程中经历热循环事件，这可能导致结构的变化，从而导致性能的变化，例如孔系统或活性金属纳米颗粒尺寸的变化。通过在长时间尺度上监测这些变化，同时保持反应或温度条件将导致对所涉及的过程的增强理解，从而可能导致改进的催化剂设计。
