Figure 2. Dehydration of ACC-SiO2 particles on incubation in solution.
SEM images of ACC-SiO2 particles after incubation in solution for (a) 0 min and (b) 500 min—scale bar, 500 nm. (c) Infrared spectra and (d) thermogravimetric analyses of ACC-SiO2 particles, showing the structural and compositional changes in the particles with incubation in solution.
