The ternary metal chalcogenide ZnIn2S4 flower-like hollow microsphere was synthesized by a solvothermal reaction of Zn(CH3COO)2·2H2O, InCl3·4H2O and l-cysteine in ethylene glycol at 160°C for 24h. The crystal structure was characterized by X-ray diffractometry. Field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) analyses show that the products consist of...
Sulfonated polystyrene (PS) microspheres have been used as template to produce hollow polyaniline (PANI) and hollow polypyrrole (PPY) microspheres in the size of range 2.2–3.4μm in diameter. The template particles were prepared by simply sulfonation of dry PS microspheres. Aniline or pyrrole was oxidatively polymerized on the surface of sulfonated PS. Dissolved with solvent, sulfonated PS cores were...
