Aminolysis Route to Monodisperse Titania Nanorods with Tunable Aspect Ratio

Abstract

High-temperature nonhydrolytic aminolysis has been developed as an approach to monodisperse titania nanocrystals by exploiting the chemical modification of reactive titanium isopropoxide with oleic acid as the chelating ligand. Its capabilities for the anisotropic growth of highly crystalline anatase titania nanocrystals (see picture) with controlled size and shape have been demonstrated.
