Parameter optimisation for electrochemically activated MoTe2

Abstract

MoTe₂ has been shown to undergo an electrochemical activation in operando, which is evidenced by a dramatic reduction of the overpotential. This work identifies the optimum reaction conditions in which MoTe₂ can be activated. The activation can be achieved by sweeping the potential between the optimal range of +0.2 V and −0.5 V (vs. NHE) for 100 cycles.
