A Simple Electrochemical Route to Metallic Phase Trilayer MoS2: evaluation as Electrocatalysts and Supercapacitors
Abstract
The development of simple, scalable and reproducible technique for the synthesis of two dimensional MoS<sub>2</sub> nanosheets is of paramount importance in the field of catalysis and energy storage devices.Current routes to produce MoS<sub>2</sub> nanosheets in reasonable quantities involve either use solution exfoliation of bulk MoS<sub>2</sub> or the intercalation of organo-lithium into bulk MoS<sub>2</sub> which then subsequently exfoliated by immersing it in water.The former process produces semiconducting 2H-MoS<sub>2</sub> nanoplatelets with smaller lateral flake size whereas the latter process produces highly conducting metallic (1T) phase monolayer MoS<sub>2</sub>.1T-MoS<sub>2</sub> nanosheets have high catalytic activity for hydrogen evolution reaction (HER) and are efficient electrode materials for supercapacitor when compared to the 2H phase.However, the feasibility of producing 1T-MoS<sub>2</sub> by organolithium intercalation is undermined by the long reaction time (2-3 days) and by its pyrophoric nature.We report a simple, bench-top electrochemical process to produce exfoliated metallic phase MoS<sub>2</sub> within two hours.By using an inert Li salt (LiClO<sub>4</sub>) as a source of lithium and a Pt counter electrode, an electrochemically lithium intercalated MoS<sub>2</sub> electrode was obtained which was subsequently exfoliated by immersing in water.Characterization of the exfoliated product using a variety of methods confirmed the formation of the 1T-phase.Remarkably, flake thickness measurement using atomic force microscopy and high-resolution transmission electron microscopy revealed that the majority of the nanosheets are trilayers.The 1T-MoS<sub>2</sub> nanosheets showed enhanced electrocatalytic activity towards hydrogen evolution compared to 2H-MoS<sub>2</sub> and are efficient materials for supercapacitor applications.Coin cells constructed from a 1T-MoS<sub>2</sub>-graphene composite achieved a volumetric capacitance of over 560 F cm<sup>-3</sup> in an aqueous system and 250 F cm<sup>-3 </sup>in a non-aqueous electrolyte with capacity retention of over 90 % after 5,000 cycles.This process is readily scalable and should ultimately support production of metallic MoS<sub>2</sub> for various applications.It can also be extended for producing 2H-MoS<sub>2 </sub>nanosheets by heating the exfoliated 1T phase.
