From: Mesoporous NiO crystals with dominantly exposed {110} reactive facets for ultrafast lithium storage

Figure 2

(a) and (b) FESEM images of NiO faceted crystals. (c) Rietveld refinement pattern of X-ray diffraction data of NiO crystals, the observed and calculated intensity are represented by red solid circle and blue solid line, respectively. The bottom purple line shows the fitting residual difference. Bragg positions are represented as light green tick. (d) N2 sorption isotherms of mesoporous faceted NiO crystals. The inset shows the pore size distributions.
