Synthesis and characterization of metal oxide nanorod brushes

Abstract

Nanorod brushes of α-Al2O3, MoO3 and ZnO have been synthesized using amorphous carbon nanotube (a-CNT) brushes as the starting material. The brushes of α-Al2O3 and MoO3 are made up of single crystalline nanorods. In the case of ZnO brushes, the nanorod bristles are made by the fusion of 15-25 nm size nanoparticles and are porous in nature. Metal oxide nanorod brushes thus obtained have been characterized bj' XRD, FESEM, TEM and Raman spectroscopy. Single crystalline ruby nanorods were obtained by introducing chromium ions during the synthesis of alumina rods. © Indian Academy of Sciences.
