2 Results and Discussion The crystal structure of the as-prepared material was investigated via the X-ray diffraction (XRD) patterns together with the Rietveld refinement, as shown in Figure 1a–c. Figure 1a displays XRD patterns of the NVO, NVO/rGO, and NVO-rGO membranes. It can be observed that the composition of materials is determined as the mixture of Na5V12O32 and NaV3O8 phase, among which, most of them could be well catalogued to the monoclinic structure of Na5V12O32 (JCPDS no. 24–1156).
