Prof. Wojciech Macyk and dr Joanna Kuncewicz are laureates of the prestigeous Foundation for Polish Science TEAM project. The project entitled “In quest of a more efficient quantum solar energy exploitation in energy downhill and uphill photocatalytic processes (INGENIOUS)” goals are to elaborate various photocatalytic and hybrid photocatalytic/catalytic materials with significantly improved efficiencies of quantum solar energy utilization.
Prof.Wojciech Macyk obtained a grant from National Science Centre within OPUS 10 programme. The project “Engineering of electronic states in semiconductor photocatalysts” is focused on design and characterization of electronic properties of semiconducting materials.
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.
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
Elżbieta Świętek has got her PhD degree. Congratulation!
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
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.
Prof. Leonardo Palmisano from University of Palermo was our guest this week.
