Comment on “Crystal growth and aggregation in suspensions of δ-MnO2 nanoparticles: implications for surface reactivity” by F. F. Marafatto, B. Lanson and J. Peña, Environ. Sci.: Nano, 2018, 5, 497

Abstract

Here, it is shown that X-ray diffraction is sensitive to the lognormal distribution of the δ-MnO2 crystallite 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.
