| Abstract: | Hierarchical structure porous MoS2/SiO2 microspheres were prepared by ultrasonic pyrolysis technique. The nanostructured MoS2/SiO2 materials were characterised by scanning electron micrograph (SEM), energy dispersive X‐ray spectroscopy (EDX), X‐ray diffraction (XRD), high‐resolution transmission electron microscope (HRTEM), as well as nitrogen isotherm. The MoS2/SiO2 microspheres, synthesised using polystyrene latex spheres as a template, showed two pore sizes: 5.8 and 68 nm. The micro‐, meso‐ and macropore volume was also calculated. Effect of PSL:SiO2 ratio on the hierarchical structure was also investigated. © 2011 Canadian Society for Chemical Engineering |
