Electrodeposition of MoS2 from dichloromethane
Abstract
The electrodeposition of MoS<sub>2</sub> from dichloromethane (CH<sub>2</sub>Cl<sub>2</sub>) using tetrabutylammonium tetrathiomolybdate ([N<sup>n</sup>Bu<sub>4</sub>]<sub>2</sub>[MoS<sub>4</sub>]) as a single source precursor is presented. The electrodeposition of MoS<sub>2</sub> from CH<sub>2</sub>Cl<sub>2</sub> requires addition of a proton donor to the electrolyte and trimethylammonium chloride (Me<sub>3</sub>NHCl)was used for this purpose. Electrochemical Quartz Crystal Microbalance(EQCM) experiments have been employed for a detailed study of theelectrochemical mechanism and to study the role of the proton donor.EQCM reveals cathodic electrodeposition of MoS<sub>2</sub> and anodic deposition of MoS<sub>3</sub> as well as an additional corrosion process where the deposited MoS<sub>3</sub> strips back into solution. The electrodeposited MoS<sub>2</sub>films are amorphous in nature. All the films were found to behomogeneous in composition across the electrode area and to bereproducible between experiments. Annealing of the as-deposited filmsunder a sulfur atmosphere results in crystalline MoS<sub>2</sub> asconfirmed by energy dispersive X-ray spectroscopy (EDX), Ramanspectroscopy and X-ray diffraction. The deposited films were smooth andplanar, as observed with scanning electron microscopy (SEM), indicating alayer-by-layer growth typical of transition metal dichalogenides.
