Fig. 5From: The Role of Growth Directors in Controlling the Morphology of Hematite NanorodsA comparison of pXRD patterns from nanorods synthesized using the two structure directors with three standard materials from the ICSD library [15,16,17]. A Phosphate-directed nanorods, prepared at 100 °C: (a)–(c) prepared with 5.75 × 10−3 M phosphate solution and aged for (a) 72 h; (b) 32 h; (c) 1 h; (d) prepared with 8.00 × 10−3 M phosphate solution and aged for 72 h; (e) prepared in the absence of phosphate ions, aged for 72 h. B 1,2-Diaminopropane-directed nanorods (f) aged for 16 h at 180 °C; (g) aged for 8 h at 180 °C; (h) aged for 1 h at 180 °C; (k) aged for 24 h at 160 °CBack to article page
