Preparation, Characterization, and Electrochemical Performance of the Hematite/Oxidized Multi-Walled Carbon Nanotubes Nanocomposite
In this research work, a hematite (α-Fe(2)O(3)) nanoparticle was prepared and then mixed with oxidized multi-walled carbon nanotubes (O-MWCNT) to form a stable suspension of an α-Fe(2)O(3)/O-MWCNTs nanocomposite. Different characterization techniques were used to explore the chemical and physical pr...

Sumario: | In this research work, a hematite (α-Fe(2)O(3)) nanoparticle was prepared and then mixed with oxidized multi-walled carbon nanotubes (O-MWCNT) to form a stable suspension of an α-Fe(2)O(3)/O-MWCNTs nanocomposite. Different characterization techniques were used to explore the chemical and physical properties of the α-Fe(2)O(3)/O-MWCNTs nanocomposite, including XRD, FT-IR, UV-Vis, and SEM. The results revealed the successful formation of the α-Fe(2)O(3) nanoparticles, and the oxidation of the MWCNT, as well as the formation of stable α-Fe(2)O(3)/O-MWCNTs nanocomposite. The electrochemical behaviour of the α-Fe(2)O(3)/O-MWCNTs nanocomposite was investigated using cyclic voltammetry (CV) and linear sweep voltammetry (LSV), and the results revealed that modification of α-Fe(2)O(3) nanoparticles with O-MWCNTs greatly enhanced electrochemical performance and capacitive behaviour, as well as cycling stability. |
