STEM HAADF Tomography of Molybdenum Disulfide with Mesoporous Structure

Datetime:2016/7/7 23:25:12hit:10500

STEM HAADF Tomography of Molybdenum Disulfide with Mesoporous Structure. A highly ordered mesoporous molybdenum disulfide has been developed for catalysis in heavy oil refining. The morphology, structure, and composition of the material have been systematically characterized with advanced electron microscopy techniques. Scanning transmission electron microscopy with high-angle annular dark field tomography has been used to investigate the porous structure to give spatial information on the nanometre scale, and offer a direct view of individual porous particles in three-dimensions. The pore-size distribution, connectivity of the pores, and the mesoporous surface area have also been analyzed and offer useful information towards catalyst design.
