Article Abstract
Herein, carbon-coated MoSe decorated MoCT MXene heterostructures (MoSe/MoCT@C) have been fabricated. MoCT works as a dual-function electron/ion conductor, which not only provides high conductivity and mechanical strength, but also prevents the severe self-aggregation of few layered MoSe nanosheets. The high reversible capacities of 405 mA h g at 100 mA g after 150 cycles and 258 mA h g at 2000 mA g after 400 cycles could be achieved for a potassium-ion battery.

Transition metal oxides, highly motivated anodes for lithium-ion batteries due to high theoretical capacity, typically afflict by inferior conductivity and significant volume variation. Architecting heterogeneous structures with distinctive interfacial features can effectively regulate the electronic structure to favor electrochemical properties. Herein, an engineered carbon-coated nanosized Fe O /Cr O heterostructure with multiple interfaces is synthesized by a facile sol-gel method and subsequent heat treatment.
