Three‐quarter‐sphere‐like γ‐AlOOH superstructures were successfully fabricated by a simple hydrothermal route exploiting the layered hydroxide structure. Several techniques such as X‐ray diffraction (XRD), FTIR spectroscopy, field‐emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), DSC thermal analysis, and nitrogen adsorption/desorption measurements were used to characterize the products. The possible formation mechanism of the three‐quarter‐sphere‐like structure was proposed and discussed. The γ‐AlOOH superstructures have high Brunauer–Emmett–Teller (BET) surface area and high adsorptive capacity. On the basis of these properties, they could be potentially used for removing chromium ions from highly toxic pollutant solutions and harmful tobacco‐specific nitrosamines (TSNAs) from cigarette smoke.
