Description
Summary:The high-yield and scalable production of single-layer ternary transition metal dichalcogenide nanosheets with approximately 66% of metallic 1T phase, including MoS sub(2x)Se sub(2(1-x)) and Mo sub(x)W sub(1-x)S sub(2) is achieved via electrochemical Li-intercalation and the exfoliation method. Thin film MoS sub(2x)Se sub(2(1-x)) nanosheets drop-cast on a fluorine-doped tin oxide substrate are used as an efficient electrocatalyst on the counter electrode for the tri-iodide reduction in a dye-sensitized solar cell.
