Characterization and adsorption characteristics of mesoporous molybdenum sulfide microspheres

Bioinspired hierarchical mesoporous MoS₂ microspheres are prepared by using pollen grains as biotemplate. Physicochemical properties of the as-prepared microspheres are characterized in detail by X-ray diffraction analysis, scanning electron microscopy and Fourier transform-infrared spectroscopy. Results indicate that the as-prepared products have a similar structure with the pollen grains, which maintain the ellipsoidal shape and the open pores networks on reticular shells. In addition, the products calcined at 800 C have an excellent adsorption activity of methyl orange (MO), which is probably related to a similar structure with the pollen grain.
