Fig. 2 shows the SEM images of products prepared at different concentration of [Bmim]Cl in EG after reaction at 160 C for 2 h. At a the molar ratio of [Bmim]Cl to EG was 0.5 (R = 0.5), the AgCl particles have cubic morphologies as shown in Fig. 2a, while the cubes are polydispersed with the sizes on the order of a few micrometers.
