Figure 6

Flower-shaped ZnO particles obtained (a–c) in the absence of CNF and (c–e) with CNF present at 0.1 g/L for reaction times of (a, d) 1 min, (b, e) 15 min, and (c, f) 60 min. (g–l) The appearance of the sea urchin structures obtained (g–i) without the incorporation of CNF and (j–l) when incorporating 0.1 g/L of CNF at the same reaction times. The calcination was made at 400 °C with the purpose of highlighting the morphological ZnO differences after temperature exposure that solely removed the cellulose with unaffected ZnO structures.
