Operando spectroscopy is widely applicable to heterogeneous catalysis, which is largely used in industrial chemistry. An example of operando methodology to monitor heterogeneous catalysis is the dehydrogenation of propane with molybdenum catalysts commonly used in industrial petroleum. [26]
Operando surface spectroscopy (XAS, NAP-XPS, FTIR, XRD) of CO oxidation and PROX on Co 3 O 4 catalysts, exploiting both static and dynamic conditions, revealed a complex reaction network. [ 10 ] [ 41 ] The presumably active (oxygen vacancy) sites were a minority species.

Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter. Spectrometry is the measurement of these interactions; a machine which performs such measurements is a spectrometer or spectrograph.
X-ray absorption near edge structure (XANES), also known as near edge X-ray absorption fine structure (NEXAFS), is a type of absorption spectroscopy that indicates the features in the X-ray absorption spectra of condensed matter due to the photoabsorption cross section for electronic transitions from an atomic core level to final states in the energy region of 50–100 eV above the selected ...
Extended X-ray absorption fine structure (EXAFS), along with X-ray absorption near edge structure , is a subset of X-ray absorption spectroscopy . Like other absorption spectroscopies , XAS techniques follow Beer's law .
Photoelectron photoion coincidence spectroscopy (PEPICO) is a combination of photoionization mass spectrometry and photoelectron spectroscopy. [1] It is largely based on the photoelectric effect . Free molecules from a gas-phase sample are ionized by incident vacuum ultraviolet (VUV) radiation.
