SYNTHESIS OF ROBUST BI-COMPONENT Co3O4-TiO2 NANOTUBE ARRAYS
Abstract
This research work studied the formation of the cobalt oxide nanostructure on the TiO2 nanotubes. Bi-component Co3O4-TiO2 nanotube arrays were synthesized via wet impregnation of Co3O4 onto the surface of TiO2 nanotube arrays followed by the heat treatment process under air, with varying the precursor molarity of cobalt complex. The morphological and structural of the bi-component nanostructure were characterised by Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-Ray (EDX), X-Ray Diffraction (XRD), and Raman spectroscopy. The deposition of the cobalt oxide nanostructure was shown on the FESEM, EDX, as well as Raman result where there were increased on the cobalt oxide nanostructure with the increased of the precursor molarity. This work provides a simple and cost-effective method to synthesis the bi-component nanostructure of Co3O4-TiO2.
