Abstract
Amrute <i>et al</i> (Reports, 25 October 2019, p. 485) claimed that no methods were able to produce high-purity α-Al<sub>2</sub>O<sub>3</sub> with surface areas greater than 100 m<sup>2</sup> g<sup>-1</sup>, even though much higher surface areas up to 253 m<sup>2</sup> g<sup>-1</sup> have been reported. Moreover, the materials they obtained could be porous aggregates and may not be 13-nm nanoparticles, as claimed.
