This review highlights the application of in situ methods, including X-ray photoelectron spectroscopy and X-ray absorption spectroscopy for monitoring oxidation states; Raman and infrared spectroscopy for analyzing chemical bonds and groups; electron spin resonance spectroscopy and total internal reflection fluorescence microscopy for studying unpaired charge carriers and radicals; photoluminescence, infrared spectroscopy and transient absorption spectroscopy for probing charge excitation and relaxation. These techniques have been employed to examine structural and compositional transformations, such as photocorrosion, metal species reduction and oxidation, and lattice oxygen loss; detect surface intermediates; investigate charge dynamics, such as charge separation and trapping; and identify active sites, including vacancies, metal-based sites, molecular sites, and active components in heterojunctions.
