Recovering Nano-Sized SnO2 from Electronic Wastes by Ultrasonic-Assisted Electrochemical Method

Tin dioxide nanoparticles were directly one-step recovered from electronic wastes using ultrasonic-assisted electrochemical method. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), which indicated that the average size of tetragonal SnO2 is 100 nm. The experiment parameters, such as the concentration of electrolyte, electrolysis current, reaction time and electrode distance, were also discussed. The proposed method is high energy efficient, non-toxic and environment-friendly, and suitable for the recovering of electronic wastes under the controllable reaction condition at room temperature.
