  • Abstract Our study was focused on preparation and capacity characteristic of the composite CNTs/β-FeOOH electrode, which was composed of different weight ratios of multi-walled carbon nanotubes (CNTs), β-FeOOH and carbon black. β-ferric oxyhydroxide (β-FeOOH) nanoparticles were synthesized by ultrasonic assisted in situ hydrolysis of the precursor ferric chloride. Different weight ratios of multi-walled carbon nanotubes (CNTs) prepared the composite CNTs/β-FeOOH electrode. FeCl3·6H2O was employed as the precursor for the synthesis of β-FeOOH nanoparticles. FeCl3·6H2O was first dissolved in distilled water to produce solution under magnetic stirring. The stable aqueous suspension was then long drawn reflux condensed in a thermostatic water bath. During this hydrolytic process, the suspension was ultra sonicated for 10 min every 1 h. After approximately 4 h, the products were cooled to room temperature and isolated by centrifugation. Finally, the products were dried in air. The composite electrode was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM),and transmission electron microscopy (TEM). The Measurement of the electrochemical properties such as capacitance was conducted using a electrochemical workstation (Jiehan 500) for cyclic voltammetry. The effects of the CNTs on the capacitive properties of the β-FeOOH electrode were studied in our work and be discussed in this paper.
