Photocatalytic Degradation of Herbicides at Titanium(IV) Oxide Modified with Metal Salts and Oxides

The doctoral thesis was focused on environmental problems related to contamination of water with herbicides: 2,4-D and 2,4,5-T. One of the most promising methods for water purification is heterogeneous photocatalysis. In this work a wide library of photocatalysts based on titanium(IV) oxide was synthetized. They were modified with different amounts (0.01-0.50%mol metal:Ti) of salts and oxides of following metals: Fe, Co, Ga, Bi, W, Mo, V and Ni. The materials were calcined at three chosen temperatures and characterised structurally and spectroscopically with XRD, UV-vis/DRS and photocurrent measurements. Their photocatalytic activity was investigated in the processes of terephthalic acid oxidation and herbicides and azure B degradation. Based on these studies the most favourable synthesis parameters were proposed: small modifier content and middle chosen calcination temperature, which result in both anatase and rutile presence in the final material. The most significant conclusion stated in this work is confirmation of indirect influence of modifiers on the photocatalytic activity of the materials. The role of modifiers is mostly observed during the photocatalyst synthesis – they influence the anatase to rutile ratio, being the main factor determining the overall photocatalytic activity of TiO2. Therefore, such modifiers are regarded as TiO2-synthesis-steering factors.

SPEA10

Few members of our group have attended the 10th European meeting on Solar Chemistry and Photocatalysis: Environmental Applications (SPEA10), held in Almería, Spain, on June 4th – 8th 2018. We have presented 3 lectures and 3 posters. The schedule of the conference was haeavily packed with lectures worth listening to. We are now back in Poland with new knowledge and ideas for future work!

TEAM

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.

 

Professorial nomination

On October 26, 2016, the President of the Republic of Poland, Andrzej Duda, nominated 99 academic teachers and employees of science and art at the Presidential Palace in Warsaw. Among the nominees there was Wojciech Macyk.
