Our new paper submitted to The Journal of Physical Chemistry Letters has been selected by the Editors to be announced on the cover page. The paper entitled “Combined Spectroscopic Methods of Determination of Density of Electronic States: Comparative Analysis of Diffuse Reflectance Spectroelectrochemistry and Reversed Double-Beam Photoacoustic Spectroscopy” (M. Kobielusz, B Nitta, A., Ohtani, W Macyk; J. Phys. Chem. Lett. 2021, 12,  3019–3025) show how complementary information on the density of electronic states of photocatalysts can be gathered using diffuse reflectance spectroelectrochemistry (SE-DRS) and reversed double-beam photoacoustic spectroscopy (RDB-PAS). The comparative analysis shows that both methods provide valuable information which can be used in understanding and predicting the photo(electro)catalytic activity of semiconductors.
