| Abstrakt: | Here, it is shown that X-ray diffraction is sensitive to the lognormal distribution of the δ-MnO2crystallite size and to the strain gradient across the nanosheet. Rigorous modeling of the two effects, which were overlooked by Marafatto et al.(Environ. Sci.: Nano, DOI 10.1039/c7en00817a), is essential to understand the influence of non-uniform microstructures on the physicochemical properties and surface reactivity of nanoparticulate δ-MnO2. |
