Abstract
This letter shows the solvothermal method synthesized MoS2 nanolayers for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) applications. The evaluated overpotential values of OER and HER of the MoS2 catalyst are 340 mV and 136 mV. The calculated values of OER and HER Tafel slopes are 189 mV dec−1 and 120 mV dec−1. In addition, the EIS spectra outline the charge-transfer resistances of 9.72 Ω and 11.87 Ω and series resistances of 0.78 Ω and 1.06 Ω of HER and OER. Furthermore, the HER reaction mechanism has been discussed to illustrate insights into the MoS2 nanolayer catalyst to explore its tremendous catalytic capabilities.
