Selective (sono)photocatalytic cleavage of lignin-inspired β–O–4 linkages to phenolics by ultrasound derived 1-D titanate nanomaterials
Qayyum, Abdul; Giannakoudakis, Dimitrios A.; Łomot, Dariusz; Colmenares-Quintero, Ramón Fernando; Nikiforow, Kostiantyn; LaGrow, Alec P.; Colmenares, Juan Carlos (Elsevier B.V., 2024-03-02)Lignin to value-added aromatic compounds is still an open challenge, since the selective cleavage of the linkages interconnecting the aromatic molecules, especially the β-O-4 ones, is not efficiently achieved yet. Herein, ... -
Tuning the physicochemical features of titanium oxide nanomaterials by ultrasound: Elevating photocatalytic selective partial oxidation of lignin-inspired aromatic alcohols
Qayyum, Abdul; Giannakoudakis, Dimitrios A.; Łomot, Dariusz; Colmenares-Quintero, Ramón Fernando; LaGrow, Alec P.; Nikiforow, Kostiantyn; Lisovytskiy, Dmytro; Colmenares, Juan Carlos (ELSEVIER, 2023)The research for “green” and economically feasible approaches such as (photo)catalysis especially for biomass valorization such as selective oxidation of biomass derived compounds like aromatic alcohols to corresponding aldehyde ... -
Ultrasound-assisted decoration of CuOx nanoclusters on TiO2 nanoparticles for additives free photocatalytic hydrogen production and biomass valorization by selective oxidation
Giannakoudakis, Dimitrios A.; Qayyum, Abdul; Nair, Vaishakh; Khan, Ayesha; Pradhan, Swaraj R.; Prekodravac, Jovana; Rekos, Kyriazis; LaGrow, Alec P.; Bondarchuk, Oleksandr; Łomot, Dariusz; Triantafyllidis, Konstantinos S.; Colmenares, Juan Carlos (Elsevier, 2021)The herein presented ultrasound-assisted ultra-wet (US-UWet) impregnation synthetic approach was followed in order to avoid the drawbacks of the conventional wet impregnation synthesis. The goal was to homogeneously decorate ...
