Members of our team participated at the 16th Conference of the Greek Catalysis Society, which was held in Mikis Theodorakis venue at the city of Chania, Crete Island, Greece, between 20-22 of October (https://www.16psc.tuc.gr/el/archi ).

Prof. Konstantinos Triantafyllidis in his Keynote Lecture presented the role of catalysis in lignocellulosic biomass valorization processes towards valuable products such as chemicals, fuels and fuel additives, with an emphasis on how to transfer the “in the lab” obtained knowledge to real-life application.

Dr. Antigoni Margellou gave an oral presentation with the title “Catalytic hydrodeoxygenation of lignin phenolic compounds and pyrolysis bio-oils”, presenting the latest results of our group in the field of lignin pyrolysis and hydrodeoxygenation reactions towards high value-added products which can be used as drop-in and aviation fuels. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 101007130 (Flexi-Green fuels).

Dr. Dimitrios Giannakoudakis participated to the conference with two poster presentations in the field of photocatalysis. The one was focusing on the photocatalytic conversion of dibenzothiophene in liquid diesel fuel as a desulfurization complementary method, with title “Photocatalytic conversion of 4,6-dimethyl-dibenzothiophene in diesel fuel using polymeric graphitic carbon nitrides (g-C3N4) and titanium oxide nanoparticles: the effect of aromatics”. The work was co-financed by the European Regional Development Fund of the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation (EPAnEK 2014-2020), under the Action “RESEARCH–CREATE–INNOVATE Β’ CALL” (Project: DESULFUR, code: Τ2ΕΔΚ-01976).

The second work was regarding the use of novel advantageous nano-photocatalysts synthesized with ultrasound assisted methods and to study in depth the mechanistic insides and how the physicochemical features affect the additives-free selective partial photocatalytic oxidation of a biomass derived model aromatic. The title of the second poster was “Photocatalytic oxidation of biomass derived chemicals by innovative nanomaterials of titanate oxide: mechanisms and reactive oxygen species”. More details about this work can be found to the recent publication in Applied Catalysis B: Environmental, with the title “Mechanistic and kinetic studies of benzyl alcohol photocatalytic oxidation by nanostructured titanium (hydro)oxides: do we know the entire story?”(https://doi.org/10.1016/j.apcatb.2022.121939).
