AB  - Here, we report for the first time a facile ultrasonic synthesis of Fe3O4 
      nanoparticles using FeCl3 and the organic solvent ethanolamine (ETA). The 
      intermediate of the ETA-Fe(II) complex produces Fe3O4 after hydrolysis and 
      hydrothermal treatment. The moderate reduction of ETA and ultrasound play an 
      important role in the synthesis of superfine Fe3O4 particles with a very high 
      specific surface area (165.05 m(2) g(-1)). The Fe3O4 nanoparticles were 
      characterized by X-ray diffraction (XRD), scanning and transmission electron 
      microscopy (SEM and TEM), high-resolution transmission electron microscopy 
      (HRTEM), and ultraviolet-visible absorption spectroscopy (UV-vis). Fe3O4 as an 
      electrode material was fabricated into a supercapacitor and characterized by 
      cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and 
      galvanostatic charge-discharge measurements. The as-synthesized Fe3O4 exhibits 
      remarkable pseudocapacitive activities including high specific capacitance (207.7 
      F g(-1) at 0.4 A g(-1)), good rate capability (90.4 F g(-1) at 10 A g(-1)), and 
      excellent cycling stability (retention 100% after 2000 cycles). This novel 
      synthetic route towards Fe3O4 is a convenient and potential way of producing a 
      secondary energy material which is expected to be applicable in the synthesis of 
      other metal oxide nanoparticles.
