Anthracite-Derived Porous Carbon@MoS Heterostructure for Elevated Lithium Storage Regulated by the Middle TiO Layer.

The rational design of MoS/carbon composites have been widely used to improve the lithium storage capability. However, their deep applications remain a big challenge due to the slow electrochemical reaction kinetics of MoS and weak bonding between MoS and carbon substrates. In this work, anthracite-derived porous carbon (APC) is sequential coated by TiO nanoparticles and MoS nanosheets via a chemical activation and two-step hydrothermal method, forming the unique APC@TiO@MoS ternary composite.
