文摘Herein,a simple yet efficient hydrothermal strategy is developed to in-situ convert multi-layered niobium-based MXene(Nb2 CTx)to hierarchical Nb2 CTx/Nb2O5 composite.In the hybrid,the Nb2O5 nanorods are well dispersed in and/or on the Nb2 CTx.Thanks to the synergetic contributions from the high capacity of Nb2O5 and superb electrical conductivity of the two-dimensional Nb2 CTx itself,the resultant Nb2 CTx/Nb2O5 hybrid exhibits excellent rate behaviors and stable long-term cycling behaviors,when evaluated as anodes for Li-ion batteries.
