Selectivity in the Ligand Functionalization of Photocatalytic Metal Oxide Nanoparticles for Phase Transfer and Self?Assembly Applications

Functionalization of photocatalytic metal oxide nanoparticles TiO2, ZnO, WO3 and CuO with amine-terminated (oleylamine) thiol-terminated (1-dodecanethiol) alkyl chained ligands was studied under ambient conditions. A high selectivity observed in the binding specificity a ligand towards these different oxides. It that oleylamine binds stably to only TiO2 WO3, while 1-dodecanethiol ZnO CuO. Similarly, polar non-polar solvent phase transfer could be achieved by using oleylamine, but not 1-dodecanethiol, contrary holds for The surface chemistry functionalized probed ATR-FTIR spectroscopy, enabled elucidate occupation at active sites. photo-stability on nanoparticle determined self-cleaning properties material. While degrade within 24 hours both UV visible light, remain unaffected. gathered insights are also highly relevant from an application point view. As example, since hydrophobic nature, they can thus self-assembled air-water interface, obtaining films demonstrated as well anti-fogging properties.
