Layered FeMo4S6 nanosheets with robust lithium storage and electrochemical hydrogen evolution

• FeMo4S6 nanosheets have been synthesized via hydrothermal method.
• The layered structure with interlayer spacing of 0.64 nm is determined.
• Large and stable lithium storage properties are obtained.
• Robust and durable electrocatalytic HER activity are achieved.

Exploration of novel advanced materials for energy conversion and storage is on the research focus. Herein, we firstly develop FeMo4S6 nanosheets via a hydrothermal process as advanced energy materials. TEM and XRD characterizations reveal that FeMo4S6 nanosheets possess distinctive layered structure with an interlayer distance of 0.64 nm and 10–14 layers in thickness. Rooted in the intriguing layered 2D structural advantages and multicomponent effect, the sample exhibits large and stable lithium storage properties when it is used as anode material for lithium-ion batteries. It is also evaluated as electrocatalyst for water splitting and shows promising catalytic activity for hydrogen evolution, including low onset overpotential and stable cycling durability.
