Abstract The catalytic oxidation of CO by O2 to form CO2 over Pt surfaces and supported catalysts is one of the most studied catalytic reactions from both fundamental and applied points of view. This review aims to show how the application of a range of time resolved, X-ray based techniques, such as X-ray diffraction XRD, Surface X-ray diffraction SXRD, total X-ray scattering-pair distribution function PDF, X-ray absorption XAFS, X-ray emission XES, and X-ray photoelectron spectroscopies XPS, applied under operando conditions and often coupled to adjunct techniques for instance mass spectrometry MS and infrared spectroscopy IR have shed new light on the structures and mechanisms at work in this most studied of systems. The aim of this review is therefore to demonstrate how a fusion of the operando philosophy with the ever augmenting capacities of modern synchrotron sources can lead to new insight and catalytic possibilities, even in the case of a process that has been intensely studied for almost 100 years.
