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.

Our new paper submitted to Dalton Transactions has been selected by the Editors to be announced at the first cover page. The paper entitled “UV and visible light active aqueous titanium dioxide colloids stabilized by surfactants” (Michał Pacia, Piotr Warszyński, Wojciech Macyk; Dalton Trans. 2014, 43, 12480-12485) describes the synthesis and activity of photosensitized titanium dioxides nanoparticles stabilized by micelles formed in the presence of TWEEN® 80 surfactant. The micelles are stable in water at pH = 7, while their structure and size depend on the surface modification of TiO2. The activity towards reactive oxygen species generation induced by visible light, stability at neutral pH in the form of transparent colloids and simple preparation are very promising features of the developed systems.

Our newest paper, entitled “Photocatalytic carboxylation of organic substrates with carbon dioxide at zinc sulfide with deposited ruthenium nanoparticles, has been published in ChemPlusChem(Tomasz Baran, Angela Dibenedetto, Michele Aresta, Krzysztof Kruczała, Wojciech Macyk,ChemPlusChem 2014, 79, 708-715). It describes a photocatalytic synthesis of carboxylic acids using CO2 and acetylacetone as substrates in the presence of ZnS-based photocatalysts with deposited ruthenium(0) nanoparticles. The paper has been published in the Early Career Series, the program of ChemPlusChem journal presenting original papers of young scientists nominated by the Editorial Board. Presented studies have been done in cooperation with the group from Bari.
