Abstract

This study examined the growth mechanism of In(OH)₃ nanocubes formed during the hydrothermal reaction of a solution containing In(NO₃)₃·6H₂O, NaOH, and H₂O₂. Regardless of the pH of the stock solution, an abnormal growth behavior was detected i.e. only a few particles grew to a very large size. However, the mean edge lengths of the nanocubes decreased significantly from 100-450 to 20-70 nm with increasing pH of the stock solution from 4 to 8.8. This was attributed to the active nucleation of In(OH)₃ nanocubes at pH 8.8 and the limitation of their growth due to the restricted source materials. The growth of In(OH)₃ nanocubes was explained in terms of a two-dimensional nucleation and growth mechanism.
