Study Of (Co)MoS2 1T-Polytype For Hydrotreating
Résumé
Crystals of MoS2 can exist as different polymorphs, displaying a range of electronic and optical properties, i.e. depending on the Mo-S coordination and the stacking order, it is possible to find three polytypes: 1T (Tetragonal), 2H (Hexagonal) and 3R (Rhombohedral). In the case of 2H and 3R polymorphs, each Mo has trigonal-prismatic coordination with the nearby S atoms, while for 1T-MoS2, Mo is coordinated in an octahedral manner.
