Modulation of MoS2@Ti electrode structure to improve electrode stability and enhance the efficiency of electrochemical reduction oxidized mercury

The electrode and MoS 2 @Ti electrochemical system were successfully optimized. However, there are problems such as easy flaking of catalytic layer and short electrode life. The use of electrode modifiers such as Nafion, Sodium dodecyl sulfate, or tin-antimony oxide interlayers attempts to optimize the bonding between the electrode substrate and the active layer. Moreover, we have successfully used foam titanium to replace the titanium plate substrate to improve the electrode stability. The adsorption reduction performance of MoS 2 @Ti electrodes and MoS 2 powders was investigated to further clarify the mechanism of MoS 2 @Ti electrochemical system. The optimization of the MoS 2 @Ti electrode reaction system was attempted by designing the combined system as well as the diaphragm system, and the fact that the reduced mercury ions were re-oxidized in the original MoS 2 @Ti system was determined.
