New cover page

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


Paweł Mikrut was nominated for the international “Scientist of the Future” Award in the category of “Exact and Technical Sciences for an Innovative Future”.

Symbol 2019 gala

Today Professor Macyk attended gala dinner at which he received the Symbol 2019 award. The Symbol is an award that shows the appreciation for actions, projects and achievements of the Group of Photocatalysis.



The Photocatalysis group has been awarded the title of the symbol of the synergy of science and business 2019.

We play SHENG with Wuhan!

The Team of Photocatalysis has been granted with almost 1.4 million zloty for the joint Polish-Chinese research project entitled “Photocatalytic reduction of carbon dioxide based on p-type semiconductors”. The project is supported by the National Science Centre, Poland (NCN) and the National Natural Science Foundation of China (NSFC). Together with the group of Prof. Jiaguo Yu from Wuhan University of Technology we will focus on the development of p-type semiconducting photocatalysts, used alone or in combination with n-type semiconductors, for a more efficient solar fuels production encompassing one- and multi-electron CO2 reduction. Briefly, the artificial photosynthesis is our goal!


On November 8 this year in the hall of the Faculty of Chemistry of the Jagiellonian University, the 15th anniversary of CITTRU was held. During the meeting prizes were awarded for constant, long-term cooperation with business partners bringing continuous and highest revenues in the JU for the provision of commercial research and expert services. The awards for commercialization of research results were given to prof. Wojciech Macyk with his team (Dr. Rafał Sadowski and Dr. Przemysław Łabuz).

OPUS project granted

Prof. Sebastian Maćkowski, prof. Joanna Niedziółka-Jönsson and prof. Wojciech Macyk  obtained a grant from National Science Centre within OPUS 12 programme. The project “Remotely light-controlled activity of dyes, proteins and catalysts: imaging, sensing and energy conversion” is intended to show that the energy of photons illuminating a nanowire can be transported to its other end, and that this energy is capable to activate and deactivate nanostructures, which are important from the point of view of imaging, sensorics or energy conversion.


SONATA project granted

Dr. Joanna Kuncewicz obtained a grant from National Science Centre within SONATA 13 programme. The project goal and title are “Studies on the interaction of semiconductors with metal-organic frameworks (MOF) and its influence on photoinduced processes”.
