Abstract

This chapter reviews the use of infrared spectroscopy and electron paramagnetic resonance (EPR) spectroscopy to investigate reaction pathways in photocatalysis. In the case of infrared spectroscopy, examples are given from four different experimental methods for obtaining spectra of photocatalysts and adsorbed species: transmission, diffuse reflectance IR Fourier transform (DRIFT), attenuated total reflectance (ATR) and reflection–absorption infrared spectroscopy (RAIRS),which is applicable to single-crystal surfaces. EPR spectroscopy has been employed to observe trapped charge species (electrons and holes) and radical intermediates produced by reaction of electrons or holes with adsorbed species. Examples of both are given.
