WET-CHEMICAL SYNTHETIZATION TO CNT-HEMATITE NANOCOMPOSITES AND CHARACTERIZATION

Abstract

Since a few decades, various types of nanomaterials differing in size, shape, composition, morphology and structure have been synthesized by distinct techniques and modifications. Also, they were characterized to explore their chemical, physical, electrical and magnetic insights. The synthetic route employed has crucially effects on the properties of synthesized nanoproduct. Carbon nanotubes (CNT) is unique, among other nanomaterials, in its ability to be doped by another elements or compound, to obtain the   features and characteristics, as per desired, in synthesizing nanocomposites and then implementing to a specific application. This study was a step to synthesis a nanocomposite that consisting hematite on the surface of CNT by wet chemical approach, which is simple, low cost, non-toxic and accessible easily in a laboratory. Further, the synthesized nanoproduct was characterized by XRD, FTIR, SEM and VSM. It implies that CNT-Hematite found in the synthesized nanostructure with some contaminations and it is a less ferromagnetic material in nature. At room temperature it shows the saturation magnetization, remnant magnetization and coercivity ~ 1.2 emu/g, 0.5 emu/g and 200 Oersted respectively, in compliance to be a suitable and contrivance candidate for lithium-ion battery or super capacitors’ applications.
