Characterization and adsorption characteristics of mesoporous molybdenum sulfide microspheres

• Bioinspired hierarchical mesoporous MoS2 nanoparticles are prepared by using pollen grains as biotemplate.
• 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.
• The biomolecules in pollen coats act as mesotemplates during the calcination process and the open macropore networks improve the accessibility of surface.
• The products calcined at 800 °C have an excellent adsorption activity of methyl orange (MO), which can be attributed to similar structure with the pollen grains.

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.
