Figure 1.

XRD patterns (a) and SEM (b, c-f) and TEM (b1) images of the hydrothermal products. The products were obtained at 150°C for 12.0 h with different molar ratios of FeCl3/H3BO3/NaOH = 2:0:6 (a1, b, b1), 2:0:4 (a2, c), 2:0:2 (a3, d, d1), 2:0.3:4 (a4, e, e1), 2:1.5:4 (a5, f, f1). Inset: aspect ratio distributions of the corresponding samples (e1, f1).
