Oxidation of ethylene glycol in the presence of molybdenum disulfide nanoplates

In the present work, after purification of molybdenite concentrate, molybdenum disulfide nanoplates were prepared by ultrasonic method. This concentrate and synthesized nanoplates were characterized through different techniques including field emission scanning electron microscopy (FE-SEM), X-ray energy dispersive spectroscopy (EDX), Xraydiffraction spectroscopy (XRD). The electrocatalytic performance of the synthesized nanoplates in the oxidation process of ethylene glycol was investigated and compared using electrochemical methods. First, the concentration of potassium hydroxide and ethylene glycol was optimized to obtain the best result in the oxidation of ethylene glycol. Based on the results, it was found that the MoS۲ catalyst in the nanostate is more effective and efficient than the bulk state. The peak current density in the presence of nanoplates was higher than the bulk molybdenum disulfide. Based on this, molybdenum disulfide nanoplates can be used as an efficient catalyst in the electrooxidation process of ethylene glycol in direct alcohol fuel cells.
