Effect of Electrolyte pH on the Inherent Electrochemistry of Layered Transition-Metal Dichalcogenides (MoS2, MoSe2, WS2, WSe2)

Original language description

We set forth to investigate the changes in the inherent oxidative peaks of different transition-metal dichalcogenides (TMDs), namely MoS2, MoSe2, WS2, and WSe2, at different electrolyte pH values. Changing the pH of the electrolyte was found to influenceand affect the inherent oxidation of TMDs, more noticeably the peak position. This could be attributed to the different reaction mechanisms and stability at the different pH values. An increase in the electrolyte pH from 0 to 8 shows a linear decrease in the peak potentials of the inherent oxidative peaks. However, small changes in peak potentials were observed at low alkaline pH levels (from 8 to 11). Beyond pH11, the emergence of an additional peak at low potentials, apart from the inherent oxidativepeak, was observed for most of the TMD materials studied. This insight into the pH dependence of the oxidation of TMD materials is of paramount importance for their electrochemical applications.
