Abstract

The effects of Na/K substitution during the synthesis of imogolite nanotubes (NTs) were studied using a combination of structural and surface analyses. These were complemented with molecular dynamics (MD) and DFT computational models. Our results provide strong experimental evidence, obtained by various characterization techniques (FT-IR, XRD, IEP, charge measurement, and HR-TEM), showing that K changes the imogolite dimensions. In fact, in the presence of K, the nanotubes become shorter and adopt a larger diameter. Moreover, the presence of the amorphous structures associated with allophane increases, even for low K concentrations. Our results underline the complexity of imogolite synthesis engineering, highlighting their high sensitivity to the chemicals that are used during synthesis.
