Upcoming conference

We are pleased to announce that the forthcoming, 21st International Symposium on the Photophysics and Photochemistry of Coordination Compounds will be held in Kraków, 5th-9th July 2015.


Scientific cooperation

The cooperation with Prof. Bunsho Ohtani and Prof. Ewa Kowalska reaches new levels – Wojciech Macyk spends one month as a visiting professor in Catalysis Research Center, Hokkaido University in Sapporo.


New publication

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 read more

Redox Characteristics of Semiconducting Photocatalytic Materials

The aim of the studies was to develop the method based on spectroelectrochemical measurements, which allows for the characterization of redox properties of various types of semiconducting materials, including determination of the impact of structural modification and surface as well as the influence of the experimental conditions on the redox properties of the semiconductors. As a part of this work a concise description of the methods used for characterization of redox properties of semiconducting photocatalytic materials was carried out and a novel model of photoinduced electron transfer read more


New publication

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.

Group meeting

Group trip

To activate not only small molecules, but also minds and bodies, on April 11-12th we enjoyed a trip to Pieniny mountains. We spent two nice days hiking in this beautiful area. (Everybody reached Trzy Korony.)


New equipement!

Our group has got a new equipment for advanced photoelectrochemical measurements. The specially designed set-up enables measurements of photocurrents as a function of the electrode potential and wavelength of incident light. In addition, the Kelvin probe can be used to characterize redox properties of studied semiconductors in the dark and upon irradiation with monochromatic light.
