Heterogeneous (solid) catalysts underpin the manufacture of > 90% of fuels and chemicals and the chemicals sector contributes £50bn yr-1 to the UK economy. The need to develop new or improved catalysts (more efficient, selective, cheaper, greener) has never been greater, with an expanding, more developed population, depletion of fossil resources and enormous concerns about global warming. The key enabler in delivering the catalysts needed is systematic insight into the molecular / atomic mechanisms that control catalyst function.This project will develop new approaches to the use of in situ X-ray and optical spectroscopies, at the analysis or resulting data. It will particularly focusing on Raman spectroscopy to provide insights into heterogeneous catalytic reactions such as selective oxidation or hydrogenation. The project will employ purposefully synthesized nanomaterials to simplify the spectroscopy data, but also catalysts prepared through wet impregnation methods close to those employed industrially as reference materials to show the applicability of the techniques/approaches used to real and 'idealized' systems.

非均相(固体)催化剂支撑了90%的燃料和化学品的制造，化工行业为英国经济贡献了500亿GB/年。随着人口的增长、更发达的人口、化石资源的枯竭以及对全球变暖的巨大担忧，开发新的或改进的催化剂(更高效、更有选择性、更便宜、更环保)的需求从未像现在这样强烈。提供所需催化剂的关键是系统地洞察控制催化剂功能的分子/原子机制。该项目将开发使用原位X射线和光学光谱进行分析或产生数据的新方法。它将特别关注拉曼光谱，以提供对选择性氧化或氢化等多相催化反应的深入了解。该项目将使用故意合成的纳米材料来简化光谱数据，但也将使用通过湿法浸渍方法制备的催化剂，这些催化剂与工业上用作参考材料的方法相似，以展示用于真实和理想系统的技术/方法的适用性。
