Development of advanced in situ methods for the study of heterogeneous catalysts

非均相（固体）催化剂支撑着90%的燃料和化学品的生产，化学品行业每年为英国经济贡献500亿英镑。随着人口的增长和发达程度的提高，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迫切。提供所需催化剂的关键因素是系统地了解控制催化剂功能的分子/原子机制。该项目将开发新的方法来使用现场x射线和光谱学，用于分析或得到的数据。它将特别关注拉曼光谱，以提供对非均相催化反应的见解，如选择性氧化或氢化。该项目将采用有目的的合成纳米材料来简化光谱数据，还将采用与工业上使用的方法接近的湿浸渍方法制备催化剂作为参考材料，以显示用于实际和“理想”系统的技术/方法的适用性。

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.
