PDOSs of the O 2p orbitals of O atoms in NaxVyOz with coordination of a zero Na and two V, b two Na and two V, and c four Na and two V. Insets are the coordination modes of the O ion. d Predicted stable configurations for V2O5/V2CO2p. e PDOS of O atoms of V2O5/V2CO2p. f XRD patterns at different 2θ values, where the arrows show the shift of the V2CTx (002) peak during the V2O5/V2CO2p synthesis. g SEM images of V2O5/V2CO2p (30%) at different magnifications. h Atomic schematic of the expected formation mechanism for the V2O5/V2CO2p heterostructure.
