Triazole-based ligands functionalized silica: Effects of ligand denticity and donors on catalytic oxidation activity of Pd nanoparticles

Preeyanuch Sangtrirutnugul

            Metal nanoparticles (MNPs) catalysts on a solid support constitute an important area of research in green catalysis. Despite their extensive studies, knowledge about the relationship between organic groups functionalized on a solid support and properties as well as catalytic activities of the resulting MNPs is still lacking. This work explores the effects of types of nitrogen donors (pyridine vs. triazole) and ligand coordination modes (tridentate vs. bidentate) on average sizes and catalytic oxidation activities of the corresponding Pd nanoparticles.

This research project was funded by Thailand Research Fund (grant number: RSA6080082) and mainly conducted at Department of Chemistry, Faculty of Science, Mahidol University. Crystal data measurement and analysis were performed at VISTEC, Thailand, in collaboration with Assoc. Prof. Khamphee Phomphrai. Knowledge obtained from this work is expected to benefit materials/inorganic chemists, academics, and students. The new triazole-based ligands reported in this project were used in our subsequent project, which has recently been accepted for publication in New Journal of Chemistry (2020). Associated SDG goals are Quality Education (4) and Partnerships for the Goals (17).
