Abstract
Being part of the development of environmentally clean and safe sustainable technologies photocatalysis is attracting increasing attention. During the last decade, great attention has been paid to the synthesis of different photocatalysts possessing high photocatalytic activity, whereas fundamental studies concerning the underlying photocatalytic processes have rarely been executed. The knowledge of these processes is, however, of utmost importance for the understanding of the reaction mechanism and thus for a better design of photocatalytic systems. The transient absorption spectroscopy (TAS) is one widely used method to study such fundamental processes. The present review paper focuses on the application of TAS in the UV-Vis-IR regions to investigate the charge carrier dynamics in ultrafast and nano-to-millisecond time regime. Hereby, the photo induced processes occurring in different materials will be discussed. Moreover, further attention is also paid to nanocomposite-based systems, in which different materials are used concomitantly to promote more efficient photocatalytic processes.
