Abstract

A catalyst (Many textbooks exist on catalysis. Look also at http://www.youtube.com/user/proftromp?feature¼watch) is a material, which increases the rate of a chemical reaction without being consumed itself and can direct the reaction to specifically form desired products. Catalytic processes are widely used in daily life: A catalyst in a car converts the toxic exhaust gases from the engine into more environmentally friendly gases. In the pharmaceutical and flavour and fragrance industry, catalysts are used to produce the required medicines or perfumes. Understanding the catalytic process itself, i.e. how the catalyst works and what factors affect its performance will help us to optimise many industrially important processes, making them more efficient and environmentally sustainable for example by producing less waste or requiring milder process conditions. A way to study these catalytic systems in detail is using spectroscopy, different types of light to take pictures or movies of the catalysts while they are working. In this chapter spectroscopic X-ray methods are described, which have been developed over the last few years and which can provide detailed electronic and structural information at relevant time-resolutions.
