Structure and surface modification of MXene for efficient Li/K-ion storage
文献摘要:
In this paper,three-dimensional(3D)hollow Ti3C2Tx MXene tubes(HTCTs)with more-O terminal groups and fewer-F groups are successfully prepared via the template-oriented electrostatic self-assembly and the subsequent annealing treatment.The obtained 3D hollow structure with large specific surface area,unique porous structure,and enlarged interlayer spacing could prevent the re-stacking of two-dimensional(2D)sheets and shorten the diffusion pathway of ions.Furthermore,density functional the-ory(DFT)calculations and electrochemical tests reveal that Ti3C2O2 MXene possesses higher adsorption ability and lower diffusion barrier for K+and Li+compared to Ti3C2 MXene dominated by-F terminal groups.Benefiting from the synergistic effect of the structural design and surface modification,the as-prepared 3D HTCTs exhibit excellent electrochemical performance as anodes for K+and Li+storage com-pared with 2D Ti3C2Tv sheets(TCSs).
