Conferences

  • 20 September 2023

In August and September, we actively participated in several conferences. Our journey began with the 15th edition of the biannual European Federation of Catalysis Societies (EFCATS) congress, EuropaCat, held in Prague. During this event, we shared our research findings through both oral and poster presentations.

Simultaneously, Professor Macyk presented our results at the French-Polish Chemistry Congress in Montpellier. Following these engagements, we seized the opportunity to showcase our work at the 8th International Conference on Semiconductor Photochemistry (SP 8), which took place in Strasbourg, France.

New cover page

  • 1 September 2023

Our recent paper, submitted to J. Phys. Chem. C, has been chosen by the editors for feature on the cover page. The manuscript, titled “Spectroscopic and Spectroelectrochemical Studies on the Redox Properties of Zinc Sulfide and Their Impact on Photocatalytic Activity,” focuses on the analysis of the electronic structure using emission and absorption UV–vis spectroscopy, along with diffuse reflectance spectroelectrochemistry (SE-DRS).

The study is centred on zinc sulfide (ZnS), a well-known photocatalyst with strong reducing properties and efficient visible light photoluminescence. Our research confirms the presence of deep electronic states within ZnS, including surface states, which significantly affect its reduction abilities. We also propose models for the electronic structures associated with potential photophysical processes, both for sulfur-rich and sulfur-deficient materials.

Remarkably, our proposed models suggest that the energy of photogenerated electrons is significantly lower than what is typically considered based on the conduction band edge level. However, our photocatalytic tests demonstrate that these electrons possess sufficient potential to drive hydrogen evolution and CO2 reduction processes

New manuscript

Our new paper, submitted to ACS Appl. Eng. Mater., has been selected by the editors to be featured on the cover page. The manuscript, entitled ‘Cobalt-/Copper-Containing Perovskites in Oxygen Evolution and Reduction Reactions,’ discusses the electronic properties of perovskite oxides as bifunctional catalysts that play a significant role in their activity in oxygen evolution and reduction reactions. These properties can be easily tuned by adsorbed molecules on the surface, primarily shifting the Fermi levels to lower energies, thus enhancing their catalytic activity.

Professor Horst Kisch Doctor honoris causa of the Jagiellonian…

  • 14 April 2023

The Senate of the Jagiellonian University upon examining the resolution of the Council of Faculty of Chemistry of the Jagiellonian University and having examined the review submitted of Prof. Antoni W. Morawski (Western Pomeranian University of Technology) and also by Prof. Adam Proń (Warsaw Univerity of Technology) supported with the resolutions of the Senates of these Universities, have decided to award Prof. Horst Kisch with the doctor honoris causa of the Jagiellonian University. He received his diploma confirming the conferment of the title of doctor honoris causa at the ceremonial meeting of the Senate of the Jagiellonian University, which took place at Collegium Maius on April 14.

Our new paper submitted to Nanoscale Advances has been selected by the Editors to be announced on the cover page. The paper entitled “Phototransformations of TiO2/Ag2O composite and their influence on photocatalytic water splitting accompanied by methanol photoreforming” (A. Jakimińska, K. Spilarewicz, W. Macyk; Nanoscale Adv., 2023, 5, 1926-1935) describes the photocatalytic water splitting and photoreforming of methanol by a TiO2/Ag2O system.
