Electron tomography and fractal aspects of MoS₂ and MoS₂/Co spheres.

ABSTRACT: A study was made by a combination of 3D electron tomography reconstruction methods and N₂ adsorption for determining the fractal dimension for nanometric MoS₂ and MoS₂/Co catalyst particles. DFT methods including Neimarke-Kiselev's method allowed to determine the particle porosity and fractal arrays at the atomic scale for the S-Mo-S(Co) 2D- layers that conform the spherically shaped catalyst particles. A structural and textural correlation was sought by further characterization performed by x-ray Rietveld refinement and Radial Distribution Function (RDF) methods, electron density maps, computational density functional theory methods and nitrogen adsorption methods altogether, for studying the structural and textural features of spherical MoS₂ an
