Incoherent, inelastic neutron spectra of TaS2(NH3), TaS2(NH3)1-χ- and TaS2(NH3)1/3(H2O)2/3 were measured in the range 250 cm-1 → 1600 cm-1 . The data suggest the presence of NH4+ cations and are in agreement with an ionic structure model proposed for these compounds

Activated carbons are materials with relevance in different industrial applications. Due to the inherent complexity and heterogeneity of their structures, an easy assignment of the species present on their surface has a challenging result. Only recently, with the possibility to collect well-resolved inelastic neutron spectra and to simulate by DFT methods more or less extended graphitic clusters, this task is starting to become feasible. Here we report our investigation on a steam activated carbon and we show that different vibrations in the region of out-of-plane C-H bending modes are specifically connected to hydrogen terminations belonging to extended and regular borders or to short and defective ones. Furthermore, simulations including heteroatoms such as oxygen allowed us to point out spectral regions with a contribution from carboxyl species.

AbstractMethods for the calculation of bulk and surface crystal potentials are described. All investigations are based on a simple ionic structure model, in which all interatomic interactions are described by Coulomb's law. Bulk potentials can be used to evaluate Madelung energies (MAPLE), Madelung factors (MF, MF*, PMF, PMF*) and potential surfaces (POPS, PEPS). Surface potentials are an instrument to predict crystal morphologies by means of the Madelung Part of Surface Energy (MAPSE) and to learn about surface adsorption and catalysis.
