AB  - Here, we first provide a facile ultrasonic-assisted synthesis of SnO using SnCl2 
      and the organic solvent of ethanolamine (ETA). The moderate alkalinity of ETA and 
      ultrasound play very important roles in the synthesis of SnO. After the 
      hydrolysis of the intermediate of ETA-Sn(II), the as-synthesized SnO nanoclusters 
      undergo assembly, amalgamation, and preferential growth to microplates in 
      hydrothermal treatment. The as-synthesized SnO was characterized by scanning 
      electron microscopy (SEM), transmission electron microscopy (TEM), 
      high-resolution transmission electron microscopy (HRTEM), ultraviolet-visible 
      absorption spectroscopy (UV-vis) and X-ray diffraction (XRD). To explore its 
      potential applications in energy storage, SnO was fabricated into a 
      supercapacitor electrode and characterized by cyclic voltammetry (CV), 
      electrochemical impedance spectroscopy (EIS), and galvanostatic charge-discharge 
      measurements. The as-synthesized SnO exhibits remarkable pseudocapacitive 
      activity including high specific capacitance (208.9 F g(-1) at 0.1 A g(-1)), good 
      rate capability (65.8 F g(-1) at 40 A g(-1)), and excellent cycling stability 
      (retention 119.3% after 10,000 cycles) for application in supercapacitors. The 
      capacitive behavior of SnO with various crystal morphologies was observed by 
      fitted EIS using an equivalent circuit. The novel synthetic route for SnO is a 
      convenient and potential way to large-scale production of microplates which is 
      expected to be applicable in the synthesis of other metal oxide nanoparticles.
