Abstract

The purpose of this study is to synthesis hematite iron oxide nanowires decorated with MWCNTs by spin coating method. The substrate hematite iron oxide nanowires were produce by thermal oxidation method with optimum parameter, 400°C and 90 minutes. MWCNTs were treated with 3M HNO-, for purification of the catalyst and to reduce agglomeration from the raw CNT. In this work, MWCNTs were dispersed in acetone, SDBS (Sodium Dodecyl Benzene Sulphonate) surfactant and DMF (Dimethylformamide) solution to get the best dispersion in morphology. Field emission scanning electron microscopy (FESEM) was used to investigate the morphology of iron oxide nanostructure/CNT formed, while X-ray diffraction (XRD), Raman spectroscopy, Photoluminescent spectroscopy (PL) and Fourier Transform Infrared Spectroscopy (FTIR) were used to investigate the structure characterization of hematite iron oxide nanostructure/CNT formed. Photocatalysis testing also had done using the UV lamp. While, UV visible to determine the ability of hematite iron oxide nanostructure/CNT as the good catalyst. The results were show the properties of hematite iron oxide as a catalyst were improved by decorated CNT on its surface. Photocatalysis testing was proved the degradation rate was increased by using sample hematite iron oxide/CNT.
