Amrute et al. (Reports, 25 October 2019, p. 485) claimed that no methods were able to produce high-purity α-Al2O3 with surface areas greater than 100 m2 g–1, even though much higher surface areas up to 253 m2 g–1 have been reported. Moreover, the materials they obtained could be porous aggregates and may not be 13-nm nanoparticles, as claimed.
