Plenary lecture by Prof. Dr. Juan Carlos Colmenares titled: Advanced carbon-based composite (piezo)photocatalysts: enviromental and organic synthesis applications


Our team leader, Juan Carlos Colmenares, actively participated in the Symposium on Catalysis — a conference in Prague, Czech Republic, 13 – 14 November 2023. It is a longstanding annual event initiated in 1969.

In the 2023 edition, Juan Carlos delivered a plenary lecture titled Advanced Carbon-Based Composite (Piezo)Photocatalysts: Environmental and Organic Synthesis Applications.”

Authored by Juan C. Colmenares, Behdokht H. Hosseini, and Dariusz Lomot, the lecture explored recent experiments on (piezo)photocatalysts, highlighting their applications in selective oxidation of organics and water decontamination within the context of lignin valorization.

The presentation showcased significant case studies, including sustainable oxidative esterification of methanol to methyl formate and phenol degradation in water using biochar-based support for TiO2, as well as efficient photocatalytic oxidation of benzyl alcohol under UV and visible light with Titania/Chitosan-Lignin nanocomposite. The lecture also covered the investigation of sonocatalytic activity for the selective oxidation of 4-hydroxy-3,5-dimethoxybenzyl Alcohol.
